allocate_ipam_pool_cidr

EC2.Client.allocate_ipam_pool_cidr(**kwargs)

Allocate a CIDR from an IPAM pool. In IPAM, an allocation is a CIDR assignment from an IPAM pool to another IPAM pool or to a resource. For more information, see Allocate CIDRs in the Amazon VPC IPAM User Guide .

Request Syntax

response = client.allocate_ipam_pool_cidr(
    DryRun=True|False,
    IpamPoolId='string',
    Cidr='string',
    NetmaskLength=123,
    ClientToken='string',
    Description='string',
    PreviewNextCidr=True|False,
    DisallowedCidrs=[
        'string',
    ]
)

Parameters

• DryRun (boolean) -- A check for whether you have the required permissions for the action without actually making the request and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .
• IpamPoolId (string) --

  [REQUIRED]

  The ID of the IPAM pool from which you would like to allocate a CIDR.

• Cidr (string) --

  The CIDR you would like to allocate from the IPAM pool. Note the following:

  • If there is no DefaultNetmaskLength allocation rule set on the pool, you must specify either the NetmaskLength or the CIDR.
  • If the DefaultNetmaskLength allocation rule is set on the pool, you can specify either the NetmaskLength or the CIDR and the DefaultNetmaskLength allocation rule will be ignored.

  Possible values: Any available IPv4 or IPv6 CIDR.

• NetmaskLength (integer) --

  The netmask length of the CIDR you would like to allocate from the IPAM pool. Note the following:

  • If there is no DefaultNetmaskLength allocation rule set on the pool, you must specify either the NetmaskLength or the CIDR.
  • If the DefaultNetmaskLength allocation rule is set on the pool, you can specify either the NetmaskLength or the CIDR and the DefaultNetmaskLength allocation rule will be ignored.

  Possible netmask lengths for IPv4 addresses are 0 - 32. Possible netmask lengths for IPv6 addresses are 0 - 128.

• ClientToken (string) --

  A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensuring Idempotency.

  This field is autopopulated if not provided.

• Description (string) -- A description for the allocation.
• PreviewNextCidr (boolean) -- A preview of the next available CIDR in a pool.
• DisallowedCidrs (list) --

  Exclude a particular CIDR range from being returned by the pool. Disallowed CIDRs are only allowed if using netmask length for allocation.

  • (string) --

    • IpamPoolAllocationId (string) --

      The ID of an allocation.

    • Description (string) --

      A description of the pool allocation.

    • ResourceId (string) --

      The ID of the resource.

    • ResourceType (string) --

      The type of the resource.

    • ResourceRegion (string) --

      The Amazon Web Services Region of the resource.

    • ResourceOwner (string) --
