allocate_ipam_pool_cidr#

EC2.Client.allocate_ipam_pool_cidr(**kwargs)#

Allocate a CIDR from an IPAM pool. The Region you use should be the IPAM pool locale. The locale is the Amazon Web Services Region where this IPAM pool is available for allocations.

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.

Note

This action creates an allocation with strong consistency. The returned CIDR will not overlap with any other allocations from the same pool.

Request Syntax

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

  • AllowedCidrs (list) –

    Include a particular CIDR range that can be returned by the pool. Allowed CIDRs are only allowed if using netmask length for allocation.

    • (string) –

  • 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) –

Return type:

dict

Response Structure

  • (dict) –

    • IpamPoolAllocation (dict) –

      Information about the allocation created.

      • Cidr (string) –

        The CIDR for the allocation. A CIDR is a representation of an IP address and its associated network mask (or netmask) and refers to a range of IP addresses. An IPv4 CIDR example is 10.24.34.0/23. An IPv6 CIDR example is 2001:DB8::/32.

      • 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) –

        The owner of the resource.
