These are the available methods:
Associates an Amazon VPC with a private hosted zone.
Warning
To perform the association, the VPC and the private hosted zone must already exist. You can't convert a public hosted zone into a private hosted zone.
Note
If you want to associate a VPC that was created by using one AWS account with a private hosted zone that was created by using a different account, the AWS account that created the private hosted zone must first submit a CreateVPCAssociationAuthorization request. Then the account that created the VPC must submit an AssociateVPCWithHostedZone request.

Comment (string) --
A complex type that describes change information about changes made to your hosted zone.
This element contains an ID that you use when performing a GetChange action to get detailed information about the change.
Check if an operation can be paginated.
Creates, changes, or deletes a resource record set, which contains authoritative DNS information for a specified domain name or subdomain name. For example, you can use ChangeResourceRecordSets to create a resource record set that routes traffic for test.example.com to a web server that has an IP address of 192.0.2.44.
Change Batches and Transactional Changes
The request body must include a document with a ChangeResourceRecordSetsRequest element. The request body contains a list of change items, known as a change batch. Change batches are considered transactional changes. When using the Amazon Route 53 API to change resource record sets, Route 53 either makes all or none of the changes in a change batch request. This ensures that Route 53 never partially implements the intended changes to the resource record sets in a hosted zone.
For example, a change batch request that deletes the CNAME record for www.example.com and creates an alias resource record set for www.example.com. Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If either the DELETE or the CREATE action fails, then both changes (plus any other changes in the batch) fail, and the original CNAME record continues to exist.
Warning
Due to the nature of transactional changes, you can't delete the same resource record set more than once in a single change batch. If you attempt to delete the same change batch more than once, Route 53 returns an InvalidChangeBatch error.
Traffic Flow
To create resource record sets for complex routing configurations, use either the traffic flow visual editor in the Route 53 console or the API actions for traffic policies and traffic policy instances. Save the configuration as a traffic policy, then associate the traffic policy with one or more domain names (such as example.com) or subdomain names (such as www.example.com), in the same hosted zone or in multiple hosted zones. You can roll back the updates if the new configuration isn't performing as expected. For more information, see Using Traffic Flow to Route DNS Traffic in the Amazon Route 53 Developer Guide .
Create, Delete, and Upsert
Use ChangeResourceRecordsSetsRequest to perform the following actions:
Syntaxes for Creating, Updating, and Deleting Resource Record Sets
The syntax for a request depends on the type of resource record set that you want to create, delete, or update, such as weighted, alias, or failover. The XML elements in your request must appear in the order listed in the syntax.
For an example for each type of resource record set, see "Examples."
Don't refer to the syntax in the "Parameter Syntax" section, which includes all of the elements for every kind of resource record set that you can create, delete, or update by using ChangeResourceRecordSets .
Change Propagation to Route 53 DNS Servers
When you submit a ChangeResourceRecordSets request, Route 53 propagates your changes to all of the Route 53 authoritative DNS servers. While your changes are propagating, GetChange returns a status of PENDING . When propagation is complete, GetChange returns a status of INSYNC . Changes generally propagate to all Route 53 name servers within 60 seconds. For more information, see GetChange .
Limits on ChangeResourceRecordSets Requests

[REQUIRED]
The ID of the hosted zone that contains the resource record sets that you want to change.
[REQUIRED]
A complex type that contains an optional comment and the Changes element.
Optional: Any comments you want to include about a change batch request.
Information about the changes to make to the record sets.
The information for each resource record set that you want to change.
The action to perform:
Warning
To delete the resource record set that is associated with a traffic policy instance, use `` DeleteTrafficPolicyInstance `` . Amazon Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
Information about the resource record set to create, delete, or update.
For ChangeResourceRecordSets requests, the name of the record that you want to create, update, or delete. For ListResourceRecordSets responses, the name of a record in the specified hosted zone.
ChangeResourceRecordSets Only
Enter a fully qualified domain name, for example, www.example.com . You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 assumes that the domain name that you specify is fully qualified. This means that Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
For information about how to specify characters other than a-z , 0-9 , and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .
You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com . Note the following:
Warning
You can't use the * wildcard for resource records sets that have a type of NS.
You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com . You can't use an * for one of the middle labels, for example, marketing.*.example.com . In addition, the * must replace the entire label; for example, you can't specify prod*.example.com .
The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
Valid values for basic resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT . When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
Valid values for multivalue answer resource record sets: A | AAAA | MX | NAPTR | PTR | SPF | SRV | TXT
Note
SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of Type is SPF . RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, "...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it." In RFC 7208, see section 14.1, The SPF DNS Record Type .
Values for alias resource record sets:
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't route traffic to a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
Resource record sets that have a routing policy other than simple: An identifier that differentiates among multiple resource record sets that have the same combination of name and type, such as multiple weighted resource record sets named acme.example.com that have a type of A. In a group of resource record sets that have the same name and type, the value of SetIdentifier must be unique for each resource record set.
For information about routing policies, see Choosing a Routing Policy in the Amazon Route 53 Developer Guide .
Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
Note
Creating latency and latency alias resource record sets in private hosted zones is not supported.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
Geolocation resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111 , create a resource record set with a Type of A and a ContinentCode of AF .
Note
Creating geolocation and geolocation alias resource record sets in private hosted zones is not supported.
If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can't create two geolocation resource record sets that specify the same geographic location.
The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
Warning
Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of CountryCode is * , which handles both queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a * resource record set, Route 53 returns a "no answer" response for queries from those locations.
You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
The two-letter code for the continent.
Valid values: AF | AN | AS | EU | OC | NA | SA
Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
The two-letter code for the country.
The code for the subdivision. Route 53 currently supports only states in the United States.
Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover ; for the other resource record set, you specify SECONDARY . In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
For more information about configuring failover for Route 53, see the following topics in the Amazon Route 53 Developer Guide :
Multivalue answer resource record sets only : To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify true for MultiValueAnswer . Note the following:
You can't create multivalue answer alias records.
The resource record cache time to live (TTL), in seconds. Note the following:
Information about the resource records to act upon.
Note
If you're creating an alias resource record set, omit ResourceRecords .
Information specific to the resource record.
Note
If you're creating an alias resource record set, omit ResourceRecord .
The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
You can specify more than one value for all record types except CNAME and SOA .
Note
If you're creating an alias resource record set, omit Value .
Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
If you're creating resource records sets for a private hosted zone, note the following:
Alias resource records sets only : The value used depends on where you want to route traffic:CloudFront distribution
Specify Z2FDTNDATAQYW2 .
Note
Alias resource record sets for CloudFront can't be created in a private zone.
Elastic Beanstalk environment
Specify the hosted zone ID for the region that you created the environment in. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
ELB load balancer
Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
An Amazon S3 bucket configured as a static website
Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
Another Route 53 resource record set in your hosted zone
Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
Alias resource record sets only: The value that you specify depends on where you want to route queries:CloudFront distribution
Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
Note
For failover alias records, you can't specify a CloudFront distribution for both the primary and secondary records. A distribution must include an alternate domain name that matches the name of the record. However, the primary and secondary records have the same name, and you can't include the same alternate domain name in more than one distribution.
Elastic Beanstalk environment
If the domain name for your Elastic Beanstalk environment includes the region that you deployed the environment in, you can create an alias record that routes traffic to the environment. For example, the domain name my-environment.*us-west-2* .elasticbeanstalk.com is a regionalized domain name.
Warning
For environments that were created before early 2016, the domain name doesn't include the region. To route traffic to these environments, you must create a CNAME record instead of an alias record. Note that you can't create a CNAME record for the root domain name. For example, if your domain name is example.com, you can create a record that routes traffic for acme.example.com to your Elastic Beanstalk environment, but you can't create a record that routes traffic for example.com to your Elastic Beanstalk environment.
For Elastic Beanstalk environments that have regionalized subdomains, specify the CNAME attribute for the environment. You can use the following methods to get the value of the CNAME attribute:
ELB load balancer
Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
Amazon S3 bucket that is configured as a static website
Specify the domain name of the Amazon S3 website endpoint that you created the bucket in, for example, s3-website-us-east-2.amazonaws.com . For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
Another Route 53 resource record set
Specify the value of the Name element for a resource record set in the current hosted zone.
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't specify the domain name for a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record that you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true , an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer or another resource record set in the hosted zone.
Note the following:
CloudFront distributions
You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
Elastic Beanstalk environments that have regionalized subdomains
If you specify an Elastic Beanstalk environment in DNSName and the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one Amazon EC2 instance.) If you set EvaluateTargetHealth to true and either no Amazon EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other available resources that are healthy, if any.
If the environment contains a single Amazon EC2 instance, there are no special requirements.
ELB load balancers
Health checking behavior depends on the type of load balancer:
Note
When you create a load balancer, you configure settings for Elastic Load Balancing health checks; they're not Route 53 health checks, but they perform a similar function. Do not create Route 53 health checks for the EC2 instances that you register with an ELB load balancer.
S3 buckets
There are no special requirements for setting EvaluateTargetHealth to true when the alias target is an S3 bucket.
Other records in the same hosted zone
If the AWS resource that you specify in DNSName is a record or a group of records (for example, a group of weighted records) but is not another alias record, we recommend that you associate a health check with all of the records in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .
For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when the status of a health check is healthy, include the HealthCheckId element and specify the ID of the applicable health check.
Route 53 determines whether a resource record set is healthy based on one of the following:
Warning
Route 53 doesn't check the health of the endpoint that is specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Route 53 checks the health of the endpoint that you specified in the health check.
For more information, see the following topics in the Amazon Route 53 Developer Guide :
When to Specify HealthCheckId
Specifying a value for HealthCheckId is useful only when Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Route 53 to base the choice in part on the status of a health check. Configuring health checks makes sense only in the following configurations:
If the health check status is healthy, Route 53 considers the alias resource record set to be healthy and includes the alias record among the records that it responds to DNS queries with.
If the health check status is unhealthy, Route 53 stops responding to DNS queries using the alias resource record set.
Note
The alias resource record set can also route traffic to a group of non-alias resource record sets that have the same routing policy, name, and type. In that configuration, associate health checks with all of the resource record sets in the group of non-alias resource record sets.
Geolocation Routing
For geolocation resource record sets, if an endpoint is unhealthy, Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the entire United States, for North America, and a resource record set that has * for CountryCode is * , which applies to all locations. If the endpoint for the state resource record set is unhealthy, Route 53 checks for healthy resource record sets in the following order until it finds a resource record set for which the endpoint is healthy:
Specifying the Health Check Endpoint by Domain Name
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com . For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (www.example.com ).
Warning
Health check results will be unpredictable if you do the following:
When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Route 53 created this resource record set for.
Warning
To delete the resource record set that is associated with a traffic policy instance, use DeleteTrafficPolicyInstance . Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.

ELB Load Balancers
If you're registering EC2 instances with an Elastic Load Balancing (ELB) load balancer, do not create Amazon Route 53 health checks for the EC2 instances. When you register an EC2 instance with a load balancer, you configure settings for an ELB health check, which performs a similar function to a Route 53 health check.

[REQUIRED]
A unique string that identifies the request and that allows you to retry a failed CreateHealthCheck request without the risk of creating two identical health checks:
[REQUIRED]
A complex type that contains settings for a new health check.
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC , omit IPAddress .
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for Port only when you specify a value for IPAddress .
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Warning
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
Warning
If you specify HTTPS for the value of Type , the endpoint must support TLS v1.0 or later.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
If you specify a value for IPAddress :
Amazon Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the preceding cases.
**If you don't specify a value for IPAddress ** :
Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName at the interval that you specify for RequestInterval . Using an IPv4 address that DNS returns, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value that you specify for Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH , the string that you want Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the response body, Route 53 considers the resource healthy.
Route 53 considers case when searching for SearchString in the response body.
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request. Each Route 53 health checker makes requests at this interval.
Warning
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval , the default value is 30 seconds.
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Route 53 console.
Warning
You can't change the value of MeasureLatency after you create a health check.
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
(CALCULATED Health Checks Only) A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
A complex type that contains one Region element for each region from which you want Amazon Route 53 health checkers to check the specified endpoint.
If you don't specify any regions, Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values .
If you update a health check to remove a region that has been performing health checks, Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.
For the current list of CloudWatch regions, see Amazon CloudWatch in the AWS Regions and Endpoints chapter of the Amazon Web Services General Reference .
The name of the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.

Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:

Creates a new public or private hosted zone. You create records in a public hosted zone to define how you want to route traffic on the internet for a domain, such as example.com, and its subdomains (apex.example.com, acme.example.com). You create records in a private hosted zone to define how you want to route traffic for a domain and its subdomains within one or more Amazon Virtual Private Clouds (Amazon VPCs).
Warning
You can't convert a public hosted zone to a private hosted zone or vice versa. Instead, you must create a new hosted zone with the same name and create new resource record sets.
For more information about charges for hosted zones, see Amazon Route 53 Pricing .
Note the following:
When you submit a CreateHostedZone request, the initial status of the hosted zone is PENDING . For public hosted zones, this means that the NS and SOA records are not yet available on all Route 53 DNS servers. When the NS and SOA records are available, the status of the zone changes to INSYNC .

Creates a configuration for DNS query logging. After you create a query logging configuration, Amazon Route 53 begins to publish log data to an Amazon CloudWatch Logs log group.
DNS query logs contain information about the queries that Route 53 receives for a specified public hosted zone, such as the following:
Route 53 edge location that responded to the DNS query
Domain or subdomain that was requested
DNS record type, such as A or AAAA
DNS response code, such as NoError or ServFail
Log Group and Resource Policy
Before you create a query logging configuration, perform the following operations.
Note
If you create a query logging configuration using the Route 53 console, Route 53 performs these operations automatically.
Note
You can't use the CloudWatch console to create or edit a resource policy. You must use the CloudWatch API, one of the AWS SDKs, or the AWS CLI.
Log Streams and Edge Locations
When Route 53 finishes creating the configuration for DNS query logging, it does the following:
The name of each log stream is in the following format:
`` hosted zone ID /edge location code ``
The edge location code is a three-letter code and an arbitrarily assigned number, for example, DFW3. The three-letter code typically corresponds with the International Air Transport Association airport code for an airport near the edge location. (These abbreviations might change in the future.) For a list of edge locations, see "The Route 53 Global Network" on the Route 53 Product Details page.
Queries That Are Logged
Query logs contain only the queries that DNS resolvers forward to Route 53. If a DNS resolver has already cached the response to a query (such as the IP address for a load balancer for example.com), the resolver will continue to return the cached response. It doesn't forward another query to Route 53 until the TTL for the corresponding resource record set expires. Depending on how many DNS queries are submitted for a resource record set, and depending on the TTL for that resource record set, query logs might contain information about only one query out of every several thousand queries that are submitted to DNS. For more information about how DNS works, see Routing Internet Traffic to Your Website or Web Application in the Amazon Route 53 Developer Guide .
Log File Format
For a list of the values in each query log and the format of each value, see Logging DNS Queries in the Amazon Route 53 Developer Guide .
Pricing
For information about charges for query logs, see Amazon CloudWatch Pricing .
How to Stop Logging
If you want Route 53 to stop sending query logs to CloudWatch Logs, delete the query logging configuration. For more information, see DeleteQueryLoggingConfig .

)
[REQUIRED]
The ID of the hosted zone that you want to log queries for. You can log queries only for public hosted zones.
[REQUIRED]
The Amazon Resource Name (ARN) for the log group that you want to Amazon Route 53 to send query logs to. This is the format of the ARN:
arn:aws:logs:region :account-id :log-group:log_group_name
To get the ARN for a log group, you can use the CloudWatch console, the DescribeLogGroups API action, the describe-log-groups command, or the applicable command in one of the AWS SDKs.

Creates a delegation set (a group of four name servers) that can be reused by multiple hosted zones. If a hosted zoned ID is specified, CreateReusableDelegationSet marks the delegation set associated with that zone as reusable.
Note
You can't associate a reusable delegation set with a private hosted zone.
For information about using a reusable delegation set to configure white label name servers, see Configuring White Label Name Servers .
The process for migrating existing hosted zones to use a reusable delegation set is comparable to the process for configuring white label name servers. You need to perform the following steps:
If you want to migrate existing hosted zones to use a reusable delegation set, the existing hosted zones can't use any of the name servers that are assigned to the reusable delegation set. If one or more hosted zones do use one or more name servers that are assigned to the reusable delegation set, you can do one of the following:

Deletes a health check.
Warning
Amazon Route 53 does not prevent you from deleting a health check even if the health check is associated with one or more resource record sets. If you delete a health check and you don't update the associated resource record sets, the future status of the health check can't be predicted and may change. This will affect the routing of DNS queries for your DNS failover configuration. For more information, see Replacing and Deleting Health Checks in the Amazon Route 53 Developer Guide .

Deletes a hosted zone.
Warning
If the name servers for the hosted zone are associated with a domain and if you want to make the domain unavailable on the Internet, we recommend that you delete the name servers from the domain to prevent future DNS queries from possibly being misrouted. If the domain is registered with Amazon Route 53, see UpdateDomainNameservers . If the domain is registered with another registrar, use the method provided by the registrar to delete name servers for the domain.
Some domain registries don't allow you to remove all of the name servers for a domain. If the registry for your domain requires one or more name servers, we recommend that you delete the hosted zone only if you transfer DNS service to another service provider, and you replace the name servers for the domain with name servers from the new provider.
You can delete a hosted zone only if it contains only the default SOA record and NS resource record sets. If the hosted zone contains other resource record sets, you must delete them before you can delete the hosted zone. If you try to delete a hosted zone that contains other resource record sets, the request fails, and Route 53 returns a HostedZoneNotEmpty error. For information about deleting records from your hosted zone, see ChangeResourceRecordSets .
To verify that the hosted zone has been deleted, do one of the following:

Response Structure
A complex type that contains the response to a GetHealthCheck request.
A complex type that contains information about one health check that is associated with the current AWS account.
The identifier that Amazon Route 53assigned to the health check when you created it. When you add or update a resource record set, you use this value to specify which health check to use. The value can be up to 64 characters long.
A unique string that you specified when you created the health check.
If the health check was created by another service, the service that created the health check. When a health check is created by another service, you can't edit or delete it using Amazon Route 53.
If the health check or hosted zone was created by another service, the service that created the resource. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
If the health check or hosted zone was created by another service, an optional description that can be provided by the other service. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
A complex type that contains detailed information about one health check.
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC , omit IPAddress .
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for Port only when you specify a value for IPAddress .
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Warning
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
Warning
If you specify HTTPS for the value of Type , the endpoint must support TLS v1.0 or later.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
If you specify a value for IPAddress :
Amazon Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the preceding cases.
**If you don't specify a value for IPAddress ** :
Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName at the interval that you specify for RequestInterval . Using an IPv4 address that DNS returns, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value that you specify for Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH , the string that you want Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the response body, Route 53 considers the resource healthy.
Route 53 considers case when searching for SearchString in the response body.
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request. Each Route 53 health checker makes requests at this interval.
Warning
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval , the default value is 30 seconds.
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Route 53 console.
Warning
You can't change the value of MeasureLatency after you create a health check.
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
(CALCULATED Health Checks Only) A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
A complex type that contains one Region element for each region from which you want Amazon Route 53 health checkers to check the specified endpoint.
If you don't specify any regions, Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values .
If you update a health check to remove a region that has been performing health checks, Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.
For the current list of CloudWatch regions, see Amazon CloudWatch in the AWS Regions and Endpoints chapter of the Amazon Web Services General Reference .
The name of the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.
Note
Route 53 supports CloudWatch alarms with the following features:
When CloudWatch has insufficient data about the metric to determine the alarm state, the status that you want Amazon Route 53 to assign to the health check:
The version of the health check. You can optionally pass this value in a call to UpdateHealthCheck to prevent overwriting another change to the health check.

Response Structure
(dict) --
A complex type that contains the response to a ListHealthChecks request.
HealthChecks (list) --
A complex type that contains one HealthCheck element for each health check that is associated with the current AWS account.
(dict) --
A complex type that contains information about one health check that is associated with the current AWS account.
Id (string) --
The identifier that Amazon Route 53assigned to the health check when you created it. When you add or update a resource record set, you use this value to specify which health check to use. The value can be up to 64 characters long.
CallerReference (string) --
A unique string that you specified when you created the health check.
LinkedService (dict) --
If the health check was created by another service, the service that created the health check. When a health check is created by another service, you can't edit or delete it using Amazon Route 53.
ServicePrincipal (string) --
If the health check or hosted zone was created by another service, the service that created the resource. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
Description (string) --
If the health check or hosted zone was created by another service, an optional description that can be provided by the other service. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
HealthCheckConfig (dict) --
A complex type that contains detailed information about one health check.
IPAddress (string) --
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC , omit IPAddress .
Port (integer) --
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for Port only when you specify a value for IPAddress .
Type (string) --
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Warning
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
Warning
If you specify HTTPS for the value of Type , the endpoint must support TLS v1.0 or later.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
ResourcePath (string) --
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
FullyQualifiedDomainName (string) --
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
If you specify a value for IPAddress :
Amazon Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the preceding cases.
**If you don't specify a value for IPAddress ** :
Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName at the interval that you specify for RequestInterval . Using an IPv4 address that DNS returns, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value that you specify for Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
SearchString (string) --
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH , the string that you want Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the response body, Route 53 considers the resource healthy.
Route 53 considers case when searching for SearchString in the response body.
RequestInterval (integer) --
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request. Each Route 53 health checker makes requests at this interval.
Warning
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval , the default value is 30 seconds.
FailureThreshold (integer) --
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
MeasureLatency (boolean) --
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Route 53 console.
Warning
You can't change the value of MeasureLatency after you create a health check.
Inverted (boolean) --
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
Disabled (boolean) --
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
HealthThreshold (integer) --
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
ChildHealthChecks (list) --
(CALCULATED Health Checks Only) A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
EnableSNI (boolean) --
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
Regions (list) --
A complex type that contains one Region element for each region from which you want Amazon Route 53 health checkers to check the specified endpoint.
If you don't specify any regions, Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values .
If you update a health check to remove a region that has been performing health checks, Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).
AlarmIdentifier (dict) --
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
Region (string) --
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.
For the current list of CloudWatch regions, see Amazon CloudWatch in the AWS Regions and Endpoints chapter of the Amazon Web Services General Reference .

If a response includes the last of the query logging configurations that are associated with the current AWS account, NextToken doesn't appear in the response.
If a response doesn't include the last of the configurations, you can get more configurations by submitting another ListQueryLoggingConfigs request. Get the value of NextToken that Amazon Route 53 returned in the previous response and include it in NextToken in the next request.
Lists the resource record sets in a specified hosted zone.
ListResourceRecordSets returns up to 100 resource record sets at a time in ASCII order, beginning at a position specified by the name and type elements.
Sort order
ListResourceRecordSets sorts results first by DNS name with the labels reversed, for example:
com.example.www.
Note the trailing dot, which can change the sort order when the record name contains characters that appear before . (decimal 46) in the ASCII table. These characters include the following: ! " # $ % & ' ( ) * + , -
When multiple records have the same DNS name, ListResourceRecordSets sorts results by the record type.
Specifying where to start listing records
You can use the name and type elements to specify the resource record set that the list begins with:
If you do not specify Name or Type
The results begin with the first resource record set that the hosted zone contains.
If you specify Name but not Type
The results begin with the first resource record set in the list whose name is greater than or equal to Name .
If you specify Type but not Name
Amazon Route 53 returns the InvalidInput error.
If you specify both Name and Type
The results begin with the first resource record set in the list whose name is greater than or equal to Name , and whose type is greater than or equal to Type .
Resource record sets that are PENDING
This action returns the most current version of the records. This includes records that are PENDING , and that are not yet available on all Route 53 DNS servers.
Changing resource record sets
To ensure that you get an accurate listing of the resource record sets for a hosted zone at a point in time, do not submit a ChangeResourceRecordSets request while you're paging through the results of a ListResourceRecordSets request. If you do, some pages may display results without the latest changes while other pages display results with the latest changes.
Displaying the next page of results
If a ListResourceRecordSets command returns more than one page of results, the value of IsTruncated is true . To display the next page of results, get the values of NextRecordName , NextRecordType , and NextRecordIdentifier (if any) from the response. Then submit another ListResourceRecordSets request, and specify those values for StartRecordName , StartRecordType , and StartRecordIdentifier .

Response Structure
(dict) --
A complex type that contains list information for the resource record set.
ResourceRecordSets (list) --
Information about multiple resource record sets.
(dict) --
Information about the resource record set to create or delete.
Name (string) --
For ChangeResourceRecordSets requests, the name of the record that you want to create, update, or delete. For ListResourceRecordSets responses, the name of a record in the specified hosted zone.
ChangeResourceRecordSets Only
Enter a fully qualified domain name, for example, www.example.com . You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 assumes that the domain name that you specify is fully qualified. This means that Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
For information about how to specify characters other than a-z , 0-9 , and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .
You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com . Note the following:
Warning
You can't use the * wildcard for resource records sets that have a type of NS.
You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com . You can't use an * for one of the middle labels, for example, marketing.*.example.com . In addition, the * must replace the entire label; for example, you can't specify prod*.example.com .
Type (string) --
The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
Valid values for basic resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT . When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
Valid values for multivalue answer resource record sets: A | AAAA | MX | NAPTR | PTR | SPF | SRV | TXT
Note
SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of Type is SPF . RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, "...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it." In RFC 7208, see section 14.1, The SPF DNS Record Type .
Values for alias resource record sets:
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't route traffic to a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
SetIdentifier (string) --
Resource record sets that have a routing policy other than simple: An identifier that differentiates among multiple resource record sets that have the same combination of name and type, such as multiple weighted resource record sets named acme.example.com that have a type of A. In a group of resource record sets that have the same name and type, the value of SetIdentifier must be unique for each resource record set.
For information about routing policies, see Choosing a Routing Policy in the Amazon Route 53 Developer Guide .
Weight (integer) --
Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
Region (string) --
Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
Note
Creating latency and latency alias resource record sets in private hosted zones is not supported.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
GeoLocation (dict) --
Geolocation resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111 , create a resource record set with a Type of A and a ContinentCode of AF .
Note
Creating geolocation and geolocation alias resource record sets in private hosted zones is not supported.
If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can't create two geolocation resource record sets that specify the same geographic location.
The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
Warning
Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of CountryCode is * , which handles both queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a * resource record set, Route 53 returns a "no answer" response for queries from those locations.
You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
ContinentCode (string) --
The two-letter code for the continent.
Valid values: AF | AN | AS | EU | OC | NA | SA
Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
CountryCode (string) --
The two-letter code for the country.
SubdivisionCode (string) --
The code for the subdivision. Route 53 currently supports only states in the United States.
Failover (string) --
Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover ; for the other resource record set, you specify SECONDARY . In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
For more information about configuring failover for Route 53, see the following topics in the Amazon Route 53 Developer Guide :
MultiValueAnswer (boolean) --
Multivalue answer resource record sets only : To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify true for MultiValueAnswer . Note the following:
You can't create multivalue answer alias records.
TTL (integer) --
The resource record cache time to live (TTL), in seconds. Note the following:
ResourceRecords (list) --
Information about the resource records to act upon.
Note
If you're creating an alias resource record set, omit ResourceRecords .
(dict) --
Information specific to the resource record.
Note
If you're creating an alias resource record set, omit ResourceRecord .
Value (string) --
The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
You can specify more than one value for all record types except CNAME and SOA .
Note
If you're creating an alias resource record set, omit Value .
AliasTarget (dict) --
Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
If you're creating resource records sets for a private hosted zone, note the following:
HostedZoneId (string) --
Alias resource records sets only : The value used depends on where you want to route traffic:
CloudFront distribution
Specify Z2FDTNDATAQYW2 .
Note
Alias resource record sets for CloudFront can't be created in a private zone.
Elastic Beanstalk environment
Specify the hosted zone ID for the region that you created the environment in. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
ELB load balancer
Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
Elastic Load Balancing table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference : Use the value that corresponds with the region that you created your load balancer in. Note that there are separate columns for Application and Classic Load Balancers and for Network Load Balancers.
AWS Management Console : Go to the Amazon EC2 page, choose Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
Elastic Load Balancing API : Use DescribeLoadBalancers to get the applicable value. For more information, see the applicable guide:
AWS CLI : Use describe-load-balancers to get the applicable value. For more information, see the applicable guide:
An Amazon S3 bucket configured as a static website
Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
Another Route 53 resource record set in your hosted zone
Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
DNSName (string) --
Alias resource record sets only: The value that you specify depends on where you want to route queries:
CloudFront distribution
Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
Note
For failover alias records, you can't specify a CloudFront distribution for both the primary and secondary records. A distribution must include an alternate domain name that matches the name of the record. However, the primary and secondary records have the same name, and you can't include the same alternate domain name in more than one distribution.
Elastic Beanstalk environment
If the domain name for your Elastic Beanstalk environment includes the region that you deployed the environment in, you can create an alias record that routes traffic to the environment. For example, the domain name my-environment.*us-west-2* .elasticbeanstalk.com is a regionalized domain name.
Warning
For environments that were created before early 2016, the domain name doesn't include the region. To route traffic to these environments, you must create a CNAME record instead of an alias record. Note that you can't create a CNAME record for the root domain name. For example, if your domain name is example.com, you can create a record that routes traffic for acme.example.com to your Elastic Beanstalk environment, but you can't create a record that routes traffic for example.com to your Elastic Beanstalk environment.
For Elastic Beanstalk environments that have regionalized subdomains, specify the CNAME attribute for the environment. You can use the following methods to get the value of the CNAME attribute:
AWS Management Console : For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide .
Elastic Beanstalk API : Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference .
AWS CLI : Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference .
ELB load balancer
Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
AWS Management Console : Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack .)
Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of DNSName . For more information, see the applicable guide:
AWS CLI : Use describe-load-balancers to get the value of DNSName . For more information, see the applicable guide:
Amazon S3 bucket that is configured as a static website
Specify the domain name of the Amazon S3 website endpoint that you created the bucket in, for example, s3-website-us-east-2.amazonaws.com . For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
Another Route 53 resource record set
Specify the value of the Name element for a resource record set in the current hosted zone.
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't specify the domain name for a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record that you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
EvaluateTargetHealth (boolean) --
Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true , an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer or another resource record set in the hosted zone.
Note the following:
CloudFront distributions
You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
Elastic Beanstalk environments that have regionalized subdomains
If you specify an Elastic Beanstalk environment in DNSName and the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one Amazon EC2 instance.) If you set EvaluateTargetHealth to true and either no Amazon EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other available resources that are healthy, if any.
If the environment contains a single Amazon EC2 instance, there are no special requirements.
ELB load balancers
Health checking behavior depends on the type of load balancer:
Note
When you create a load balancer, you configure settings for Elastic Load Balancing health checks; they're not Route 53 health checks, but they perform a similar function. Do not create Route 53 health checks for the EC2 instances that you register with an ELB load balancer.
S3 buckets
There are no special requirements for setting EvaluateTargetHealth to true when the alias target is an S3 bucket.
Other records in the same hosted zone
If the AWS resource that you specify in DNSName is a record or a group of records (for example, a group of weighted records) but is not another alias record, we recommend that you associate a health check with all of the records in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .
For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .
HealthCheckId (string) --
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when the status of a health check is healthy, include the HealthCheckId element and specify the ID of the applicable health check.
Route 53 determines whether a resource record set is healthy based on one of the following:
Warning
Route 53 doesn't check the health of the endpoint that is specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Route 53 checks the health of the endpoint that you specified in the health check.
For more information, see the following topics in the Amazon Route 53 Developer Guide :
When to Specify HealthCheckId
Specifying a value for HealthCheckId is useful only when Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Route 53 to base the choice in part on the status of a health check. Configuring health checks makes sense only in the following configurations:
If the health check status is healthy, Route 53 considers the alias resource record set to be healthy and includes the alias record among the records that it responds to DNS queries with.
If the health check status is unhealthy, Route 53 stops responding to DNS queries using the alias resource record set.
Note
The alias resource record set can also route traffic to a group of non-alias resource record sets that have the same routing policy, name, and type. In that configuration, associate health checks with all of the resource record sets in the group of non-alias resource record sets.
Geolocation Routing
For geolocation resource record sets, if an endpoint is unhealthy, Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the entire United States, for North America, and a resource record set that has * for CountryCode is * , which applies to all locations. If the endpoint for the state resource record set is unhealthy, Route 53 checks for healthy resource record sets in the following order until it finds a resource record set for which the endpoint is healthy:
Specifying the Health Check Endpoint by Domain Name
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com . For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (www.example.com ).
Warning
Health check results will be unpredictable if you do the following:
TrafficPolicyInstanceId (string) --
When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Route 53 created this resource record set for.
Warning
To delete the resource record set that is associated with a traffic policy instance, use DeleteTrafficPolicyInstance . Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
IsTruncated (boolean) --
A flag that indicates whether more resource record sets remain to be listed. If your results were truncated, you can make a follow-up pagination request by using the NextRecordName element.
NextRecordName (string) --
If the results were truncated, the name of the next record in the list.
This element is present only if IsTruncated is true.
NextRecordType (string) --
If the results were truncated, the type of the next record in the list.
This element is present only if IsTruncated is true.
NextRecordIdentifier (string) --
Resource record sets that have a routing policy other than simple: If results were truncated for a given DNS name and type, the value of SetIdentifier for the next resource record set that has the current DNS name and type.
For information about routing policies, see Choosing a Routing Policy in the Amazon Route 53 Developer Guide .

[REQUIRED]
The ID for the health check for which you want detailed information. When you created the health check, CreateHealthCheck returned the ID in the response, in the HealthCheckId element.
A sequential counter that Amazon Route 53 sets to 1 when you create a health check and increments by 1 each time you update settings for the health check.
We recommend that you use GetHealthCheck or ListHealthChecks to get the current value of HealthCheckVersion for the health check that you want to update, and that you include that value in your UpdateHealthCheck request. This prevents Route 53 from overwriting an intervening update:
The IPv4 or IPv6 IP address for the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address that is returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance never changes. For more information, see the applicable documentation:
Note
If a health check already has a value for IPAddress , you can change the value. However, you can't update an existing health check to add or remove the value of IPAddress .
For more information, see UpdateHealthCheckRequest$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
The path that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
Specify this value only if you want to change it.
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
Note
If a health check already has a value for IPAddress , you can change the value. However, you can't update an existing health check to add or remove the value of IPAddress .
If you specify a value for IPAddress :
Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the above cases.
If you don't specify a value for IPAddress :
If you don't specify a value for IPAddress , Route 53 sends a DNS request to the domain that you specify in FullyQualifiedDomainName at the interval you specify in RequestInterval . Using an IPv4 address that is returned by DNS, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value of Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the ChildHealthChecks and ChildHealthCheck elements.
Note the following:
A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
A complex type that contains one Region element for each region that you want Amazon Route 53 health checkers to check the specified endpoint from.
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.
For the current list of CloudWatch regions, see Amazon CloudWatch in the AWS Regions and Endpoints chapter of the Amazon Web Services General Reference .
The name of the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.
Note
Route 53 supports CloudWatch alarms with the following features:
When CloudWatch has insufficient data about the metric to determine the alarm state, the status that you want Amazon Route 53 to assign to the health check:
A complex type that contains one ResettableElementName element for each element that you want to reset to the default value. Valid values for ResettableElementName include the following:

CallerReference (string) --
A unique string that you specified when you created the health check.
LinkedService (dict) --
If the health check was created by another service, the service that created the health check. When a health check is created by another service, you can't edit or delete it using Amazon Route 53.

Description (string) --
If the health check or hosted zone was created by another service, an optional description that can be provided by the other service. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
HealthCheckConfig (dict) --
A complex type that contains detailed information about one health check.
IPAddress (string) --
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC , omit IPAddress .
Port (integer) --
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for Port only when you specify a value for IPAddress .
Type (string) --
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Warning
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
Warning
If you specify HTTPS for the value of Type , the endpoint must support TLS v1.0 or later.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
ResourcePath (string) --
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
FullyQualifiedDomainName (string) --
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
If you specify a value for IPAddress :
Amazon Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the preceding cases.
**If you don't specify a value for IPAddress ** :
Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName at the interval that you specify for RequestInterval . Using an IPv4 address that DNS returns, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value that you specify for Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
SearchString (string) --
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH , the string that you want Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the response body, Route 53 considers the resource healthy.
Route 53 considers case when searching for SearchString in the response body.
RequestInterval (integer) --
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request. Each Route 53 health checker makes requests at this interval.
Warning
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval , the default value is 30 seconds.
FailureThreshold (integer) --
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
MeasureLatency (boolean) --
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Route 53 console.
Warning
You can't change the value of MeasureLatency after you create a health check.
Inverted (boolean) --
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
Disabled (boolean) --
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
HealthThreshold (integer) --
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
ChildHealthChecks (list) --
(CALCULATED Health Checks Only) A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
EnableSNI (boolean) --
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
Regions (list) --
A complex type that contains one Region element for each region from which you want Amazon Route 53 health checkers to check the specified endpoint.
If you don't specify any regions, Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values .
If you update a health check to remove a region that has been performing health checks, Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).
AlarmIdentifier (dict) --
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
Region (string) --
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.

If the health check or hosted zone was created by another service, the service that created the resource. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
If the health check or hosted zone was created by another service, an optional description that can be provided by the other service. When a resource is created by another service, you can't edit or delete it using Amazon Route 53.
A complex type that contains detailed information about one health check.
The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53 to perform health checks on. If you don't specify a value for IPAddress , Route 53 sends a DNS request to resolve the domain name that you specify in FullyQualifiedDomainName at the interval that you specify in RequestInterval . Using an IP address returned by DNS, Route 53 then checks the health of the endpoint.
Use one of the following formats for the value of IPAddress :
If the endpoint is an EC2 instance, we recommend that you create an Elastic IP address, associate it with your EC2 instance, and specify the Elastic IP address for IPAddress . This ensures that the IP address of your instance will never change.
For more information, see HealthCheckConfig$FullyQualifiedDomainName .
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
When the value of Type is CALCULATED or CLOUDWATCH_METRIC , omit IPAddress .
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Specify a value for Port only when you specify a value for IPAddress .
The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Warning
You can't change the value of Type after you create a health check.
You can create the following types of health checks:
Warning
If you specify HTTPS for the value of Type , the endpoint must support TLS v1.0 or later.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
The path, if any, that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example, the file /docs/route53-health-check.html. You can also include query string parameters, for example, /welcome.html?language=jp&login=y .
Amazon Route 53 behavior depends on whether you specify a value for IPAddress .
If you specify a value for IPAddress :
Amazon Route 53 sends health check requests to the specified IPv4 or IPv6 address and passes the value of FullyQualifiedDomainName in the Host header for all health checks except TCP health checks. This is typically the fully qualified DNS name of the endpoint on which you want Route 53 to perform health checks.
When Route 53 checks the health of an endpoint, here is how it constructs the Host header:
If you don't specify a value for FullyQualifiedDomainName , Route 53 substitutes the value of IPAddress in the Host header in each of the preceding cases.
**If you don't specify a value for IPAddress ** :
Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName at the interval that you specify for RequestInterval . Using an IPv4 address that DNS returns, Route 53 then checks the health of the endpoint.
Note
If you don't specify a value for IPAddress , Route 53 uses only IPv4 to send health checks to the endpoint. If there's no resource record set with a type of A for the name that you specify for FullyQualifiedDomainName , the health check fails with a "DNS resolution failed" error.
If you want to check the health of weighted, latency, or failover resource record sets and you choose to specify the endpoint only by FullyQualifiedDomainName , we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (www.example.com).
Warning
In this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and you then associate the health check with those resource record sets, health check results will be unpredictable.
In addition, if the value that you specify for Type is HTTP , HTTPS , HTTP_STR_MATCH , or HTTPS_STR_MATCH , Route 53 passes the value of FullyQualifiedDomainName in the Host header, as it does when you specify a value for IPAddress . If the value of Type is TCP , Route 53 doesn't pass a Host header.
If the value of Type is HTTP_STR_MATCH or HTTP_STR_MATCH , the string that you want Amazon Route 53 to search for in the response body from the specified resource. If the string appears in the response body, Route 53 considers the resource healthy.
Route 53 considers case when searching for SearchString in the response body.
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request. Each Route 53 health checker makes requests at this interval.
Warning
You can't change the value of RequestInterval after you create a health check.
If you don't specify a value for RequestInterval , the default value is 30 seconds.
The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide .
If you don't specify a value for FailureThreshold , the default value is three health checks.
Specify whether you want Amazon Route 53 to measure the latency between health checkers in multiple AWS regions and your endpoint, and to display CloudWatch latency graphs on the Health Checks page in the Route 53 console.
Warning
You can't change the value of MeasureLatency after you create a health check.
Specify whether you want Amazon Route 53 to invert the status of a health check, for example, to consider a health check unhealthy when it otherwise would be considered healthy.
Stops Route 53 from performing health checks. When you disable a health check, here's what happens:
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources. If you want to stop routing traffic to a resource, change the value of UpdateHealthCheckRequest$Inverted .
Charges for a health check still apply when the health check is disabled. For more information, see Amazon Route 53 Pricing .
The number of child health checks that are associated with a CALCULATED health that Amazon Route 53 must consider healthy for the CALCULATED health check to be considered healthy. To specify the child health checks that you want to associate with a CALCULATED health check, use the HealthCheckConfig$ChildHealthChecks and HealthCheckConfig$ChildHealthChecks elements.
Note the following:
(CALCULATED Health Checks Only) A complex type that contains one ChildHealthCheck element for each health check that you want to associate with a CALCULATED health check.
Specify whether you want Amazon Route 53 to send the value of FullyQualifiedDomainName to the endpoint in the client_hello message during TLS negotiation. This allows the endpoint to respond to HTTPS health check requests with the applicable SSL/TLS certificate.
Some endpoints require that HTTPS requests include the host name in the client_hello message. If you don't enable SNI, the status of the health check will be SSL alert handshake_failure . A health check can also have that status for other reasons. If SNI is enabled and you're still getting the error, check the SSL/TLS configuration on your endpoint and confirm that your certificate is valid.
The SSL/TLS certificate on your endpoint includes a domain name in the Common Name field and possibly several more in the Subject Alternative Names field. One of the domain names in the certificate should match the value that you specify for FullyQualifiedDomainName . If the endpoint responds to the client_hello message with a certificate that does not include the domain name that you specified in FullyQualifiedDomainName , a health checker will retry the handshake. In the second attempt, the health checker will omit FullyQualifiedDomainName from the client_hello message.
A complex type that contains one Region element for each region from which you want Amazon Route 53 health checkers to check the specified endpoint.
If you don't specify any regions, Route 53 health checkers automatically performs checks from all of the regions that are listed under Valid Values .
If you update a health check to remove a region that has been performing health checks, Route 53 will briefly continue to perform checks from that region to ensure that some health checkers are always checking the endpoint (for example, if you replace three regions with four different regions).
A complex type that identifies the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether the specified health check is healthy.
For the CloudWatch alarm that you want Route 53 health checkers to use to determine whether this health check is healthy, the region that the alarm was created in.
For the current list of CloudWatch regions, see Amazon CloudWatch in the AWS Regions and Endpoints chapter of the Amazon Web Services General Reference .
The name of the CloudWatch alarm that you want Amazon Route 53 health checkers to use to determine whether this health check is healthy.
Note
Route 53 supports CloudWatch alarms with the following features:
When CloudWatch has insufficient data about the metric to determine the alarm state, the status that you want Amazon Route 53 to assign to the health check:
The version of the health check. You can optionally pass this value in a call to UpdateHealthCheck to prevent overwriting another change to the health check.
A complex type that contains information about the CloudWatch alarm that Amazon Route 53 is monitoring for this health check.
For the metric that the CloudWatch alarm is associated with, the number of periods that the metric is compared to the threshold.
For the metric that the CloudWatch alarm is associated with, the value the metric is compared with.
For the metric that the CloudWatch alarm is associated with, the arithmetic operation that is used for the comparison.
For the metric that the CloudWatch alarm is associated with, the duration of one evaluation period in seconds.
The name of the CloudWatch metric that the alarm is associated with.
The namespace of the metric that the alarm is associated with. For more information, see Amazon CloudWatch Namespaces, Dimensions, and Metrics Reference in the Amazon CloudWatch User Guide .
For the metric that the CloudWatch alarm is associated with, the statistic that is applied to the metric.
For the metric that the CloudWatch alarm is associated with, a complex type that contains information about the dimensions for the metric. For information, see Amazon CloudWatch Namespaces, Dimensions, and Metrics Reference in the Amazon CloudWatch User Guide .
For the metric that the CloudWatch alarm is associated with, a complex type that contains information about one dimension.
For the metric that the CloudWatch alarm is associated with, the name of one dimension.
For the metric that the CloudWatch alarm is associated with, the value of one dimension.
For the second and subsequent calls to ListHealthChecks , Marker is the value that you specified for the marker parameter in the previous request.
A flag that indicates whether there are more health checks to be listed. If the response was truncated, you can get the next group of health checks by submitting another ListHealthChecks request and specifying the value of NextMarker in the marker parameter.
The value that you specified for the maxitems parameter in the call to ListHealthChecks that produced the current response.

(dict) --
A complex type that contains list information for the resource record set.
ResourceRecordSets (list) --
Information about multiple resource record sets.

Information about the resource record set to create or delete.
Name (string) --
For ChangeResourceRecordSets requests, the name of the record that you want to create, update, or delete. For ListResourceRecordSets responses, the name of a record in the specified hosted zone.
ChangeResourceRecordSets Only
Enter a fully qualified domain name, for example, www.example.com . You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 assumes that the domain name that you specify is fully qualified. This means that Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
For information about how to specify characters other than a-z , 0-9 , and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .
You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com . Note the following:
Warning
You can't use the * wildcard for resource records sets that have a type of NS.
You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com . You can't use an * for one of the middle labels, for example, marketing.*.example.com . In addition, the * must replace the entire label; for example, you can't specify prod*.example.com .
Type (string) --
The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
Valid values for basic resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT . When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
Valid values for multivalue answer resource record sets: A | AAAA | MX | NAPTR | PTR | SPF | SRV | TXT
Note
SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of Type is SPF . RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, "...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it." In RFC 7208, see section 14.1, The SPF DNS Record Type .
Values for alias resource record sets:
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't route traffic to a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
SetIdentifier (string) --
Resource record sets that have a routing policy other than simple: An identifier that differentiates among multiple resource record sets that have the same combination of name and type, such as multiple weighted resource record sets named acme.example.com that have a type of A. In a group of resource record sets that have the same name and type, the value of SetIdentifier must be unique for each resource record set.
For information about routing policies, see Choosing a Routing Policy in the Amazon Route 53 Developer Guide .
Weight (integer) --
Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
Region (string) --
Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
Note
Creating latency and latency alias resource record sets in private hosted zones is not supported.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
GeoLocation (dict) --
Geolocation resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111 , create a resource record set with a Type of A and a ContinentCode of AF .
Note
Creating geolocation and geolocation alias resource record sets in private hosted zones is not supported.
If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can't create two geolocation resource record sets that specify the same geographic location.
The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
Warning
Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of CountryCode is * , which handles both queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a * resource record set, Route 53 returns a "no answer" response for queries from those locations.
You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
ContinentCode (string) --
The two-letter code for the continent.
Valid values: AF | AN | AS | EU | OC | NA | SA
Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
CountryCode (string) --
The two-letter code for the country.
SubdivisionCode (string) --
The code for the subdivision. Route 53 currently supports only states in the United States.
Failover (string) --
Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover ; for the other resource record set, you specify SECONDARY . In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
For more information about configuring failover for Route 53, see the following topics in the Amazon Route 53 Developer Guide :
MultiValueAnswer (boolean) --
Multivalue answer resource record sets only : To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify true for MultiValueAnswer . Note the following:
You can't create multivalue answer alias records.
TTL (integer) --
The resource record cache time to live (TTL), in seconds. Note the following:
ResourceRecords (list) --
Information about the resource records to act upon.
Note
If you're creating an alias resource record set, omit ResourceRecords .
(dict) --
Information specific to the resource record.
Note
If you're creating an alias resource record set, omit ResourceRecord .
Value (string) --
The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
You can specify more than one value for all record types except CNAME and SOA .
Note
If you're creating an alias resource record set, omit Value .
AliasTarget (dict) --
Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
If you're creating resource records sets for a private hosted zone, note the following:
HostedZoneId (string) --
Alias resource records sets only : The value used depends on where you want to route traffic:
CloudFront distribution
Specify Z2FDTNDATAQYW2 .
Note
Alias resource record sets for CloudFront can't be created in a private zone.
Elastic Beanstalk environment
Specify the hosted zone ID for the region that you created the environment in. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
ELB load balancer
Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
Elastic Load Balancing table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference : Use the value that corresponds with the region that you created your load balancer in. Note that there are separate columns for Application and Classic Load Balancers and for Network Load Balancers.
AWS Management Console : Go to the Amazon EC2 page, choose Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
Elastic Load Balancing API : Use DescribeLoadBalancers to get the applicable value. For more information, see the applicable guide:
AWS CLI : Use describe-load-balancers to get the applicable value. For more information, see the applicable guide:
An Amazon S3 bucket configured as a static website
Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
Another Route 53 resource record set in your hosted zone
Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
DNSName (string) --
Alias resource record sets only: The value that you specify depends on where you want to route queries:
CloudFront distribution
Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
Note
For failover alias records, you can't specify a CloudFront distribution for both the primary and secondary records. A distribution must include an alternate domain name that matches the name of the record. However, the primary and secondary records have the same name, and you can't include the same alternate domain name in more than one distribution.
Elastic Beanstalk environment
If the domain name for your Elastic Beanstalk environment includes the region that you deployed the environment in, you can create an alias record that routes traffic to the environment. For example, the domain name my-environment.*us-west-2* .elasticbeanstalk.com is a regionalized domain name.
Warning
For environments that were created before early 2016, the domain name doesn't include the region. To route traffic to these environments, you must create a CNAME record instead of an alias record. Note that you can't create a CNAME record for the root domain name. For example, if your domain name is example.com, you can create a record that routes traffic for acme.example.com to your Elastic Beanstalk environment, but you can't create a record that routes traffic for example.com to your Elastic Beanstalk environment.
For Elastic Beanstalk environments that have regionalized subdomains, specify the CNAME attribute for the environment. You can use the following methods to get the value of the CNAME attribute:
AWS Management Console : For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide .
Elastic Beanstalk API : Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference .
AWS CLI : Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference .
ELB load balancer
Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
AWS Management Console : Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack .)
Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of DNSName . For more information, see the applicable guide:
AWS CLI : Use describe-load-balancers to get the value of DNSName . For more information, see the applicable guide:
Amazon S3 bucket that is configured as a static website
Specify the domain name of the Amazon S3 website endpoint that you created the bucket in, for example, s3-website-us-east-2.amazonaws.com . For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
Another Route 53 resource record set
Specify the value of the Name element for a resource record set in the current hosted zone.
Note
If you're creating an alias record that has the same name as the hosted zone (known as the zone apex), you can't specify the domain name for a record for which the value of Type is CNAME . This is because the alias record must have the same type as the record that you're routing traffic to, and creating a CNAME record for the zone apex isn't supported even for an alias record.
EvaluateTargetHealth (boolean) --
Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true , an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer or another resource record set in the hosted zone.
Note the following:
CloudFront distributions
You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
Elastic Beanstalk environments that have regionalized subdomains
If you specify an Elastic Beanstalk environment in DNSName and the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one Amazon EC2 instance.) If you set EvaluateTargetHealth to true and either no Amazon EC2 instances are healthy or the load balancer itself is unhealthy, Route 53 routes queries to other available resources that are healthy, if any.
If the environment contains a single Amazon EC2 instance, there are no special requirements.
ELB load balancers
Health checking behavior depends on the type of load balancer:
Note
When you create a load balancer, you configure settings for Elastic Load Balancing health checks; they're not Route 53 health checks, but they perform a similar function. Do not create Route 53 health checks for the EC2 instances that you register with an ELB load balancer.
S3 buckets
There are no special requirements for setting EvaluateTargetHealth to true when the alias target is an S3 bucket.
Other records in the same hosted zone
If the AWS resource that you specify in DNSName is a record or a group of records (for example, a group of weighted records) but is not another alias record, we recommend that you associate a health check with all of the records in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .
For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .
HealthCheckId (string) --
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when the status of a health check is healthy, include the HealthCheckId element and specify the ID of the applicable health check.
Route 53 determines whether a resource record set is healthy based on one of the following:
Warning
Route 53 doesn't check the health of the endpoint that is specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Route 53 checks the health of the endpoint that you specified in the health check.
For more information, see the following topics in the Amazon Route 53 Developer Guide :
When to Specify HealthCheckId
Specifying a value for HealthCheckId is useful only when Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Route 53 to base the choice in part on the status of a health check. Configuring health checks makes sense only in the following configurations:
If the health check status is healthy, Route 53 considers the alias resource record set to be healthy and includes the alias record among the records that it responds to DNS queries with.
If the health check status is unhealthy, Route 53 stops responding to DNS queries using the alias resource record set.
Note
The alias resource record set can also route traffic to a group of non-alias resource record sets that have the same routing policy, name, and type. In that configuration, associate health checks with all of the resource record sets in the group of non-alias resource record sets.
Geolocation Routing
For geolocation resource record sets, if an endpoint is unhealthy, Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the entire United States, for North America, and a resource record set that has * for CountryCode is * , which applies to all locations. If the endpoint for the state resource record set is unhealthy, Route 53 checks for healthy resource record sets in the following order until it finds a resource record set for which the endpoint is healthy:
Specifying the Health Check Endpoint by Domain Name
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com . For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (www.example.com ).
Warning
Health check results will be unpredictable if you do the following:
TrafficPolicyInstanceId (string) --
When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Route 53 created this resource record set for.
Warning
To delete the resource record set that is associated with a traffic policy instance, use DeleteTrafficPolicyInstance . Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
IsTruncated (boolean) --
A flag that indicates whether more resource record sets remain to be listed. If your results were truncated, you can make a follow-up pagination request by using the NextRecordName element.
MaxItems (string) --
The maximum number of records you requested.
NextToken (string) --
A token to resume pagination.
The available waiters are:
waiter = client.get_waiter('resource_record_sets_changed')
Polls Route53.Client.get_change() every 30 seconds until a successful state is reached. An error is returned after 60 failed checks.
