assign_private_ip_addresses¶

assign_private_ip_addresses(**kwargs)¶

Assigns one or more secondary private IP addresses to the specified network interface.

You can specify one or more specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned within the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For information about instance types, see Instance Types in the Amazon Elastic Compute Cloud User Guide . For more information about Elastic IP addresses, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide .

When you move a secondary private IP address to another network interface, any Elastic IP address that is associated with the IP address is also moved.

Remapping an IP address is an asynchronous operation. When you move an IP address from one network interface to another, check network/interfaces/macs/mac/local-ipv4s in the instance metadata to confirm that the remapping is complete.

You must specify either the IP addresses or the IP address count in the request.

You can optionally use Prefix Delegation on the network interface. You must specify either the IPv4 Prefix Delegation prefixes, or the IPv4 Prefix Delegation count. For information, see Assigning prefixes to Amazon EC2 network interfaces in the Amazon Elastic Compute Cloud User Guide .

Request Syntax

response = network_interface.assign_private_ip_addresses(
    AllowReassignment=True|False,
    PrivateIpAddresses=[
        'string',
    ],
    SecondaryPrivateIpAddressCount=123,
    Ipv4Prefixes=[
        'string',
    ],
    Ipv4PrefixCount=123
)

Parameters

AllowReassignment (boolean) -- Indicates whether to allow an IP address that is already assigned to another network interface or instance to be reassigned to the specified network interface.
PrivateIpAddresses (list) --
The IP addresses to be assigned as a secondary private IP address to the network interface. You can't specify this parameter when also specifying a number of secondary IP addresses.

If you don't specify an IP address, Amazon EC2 automatically selects an IP address within the subnet range.
- (string) --
SecondaryPrivateIpAddressCount (integer) -- The number of secondary IP addresses to assign to the network interface. You can't specify this parameter when also specifying private IP addresses.
Ipv4Prefixes (list) --
One or more IPv4 prefixes assigned to the network interface. You cannot use this option if you use the Ipv4PrefixCount option.
- (string) --
Ipv4PrefixCount (integer) -- The number of IPv4 prefixes that Amazon Web Services automatically assigns to the network interface. You cannot use this option if you use the Ipv4 Prefixes option.
