Get a list of all the CIDR allocations in 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.


If you use this action after AllocateIpamPoolCidr or ReleaseIpamPoolAllocation , note that all EC2 API actions follow an eventual consistency model.

See also: AWS API Documentation

get-ipam-pool-allocations is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: IpamPoolAllocations


[--dry-run | --no-dry-run]
--ipam-pool-id <value>
[--ipam-pool-allocation-id <value>]
[--filters <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]


--dry-run | --no-dry-run (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 .

--ipam-pool-id (string)

The ID of the IPAM pool you want to see the allocations for.

--ipam-pool-allocation-id (string)

The ID of the allocation.

--filters (list)

One or more filters for the request. For more information about filtering, see Filtering CLI output .


A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.


Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

    "Name": "string",
    "Values": ["string", ...]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To get the CIDRs allocated from an IPAM pool

The following get-ipam-pool-allocations example gets the CIDRs allocated from an IPAM pool.


aws ec2 get-ipam-pool-allocations \
    --ipam-pool-id ipam-pool-0533048da7d823723 \
    --filters Name=ipam-pool-allocation-id,Values=ipam-pool-alloc-0e6186d73999e47389266a5d6991e6220


aws ec2 get-ipam-pool-allocations ^
    --ipam-pool-id ipam-pool-0533048da7d823723 ^
    --filters Name=ipam-pool-allocation-id,Values=ipam-pool-alloc-0e6186d73999e47389266a5d6991e6220


    "IpamPoolAllocations": [
            "Cidr": "",
            "IpamPoolAllocationId": "ipam-pool-alloc-0e6186d73999e47389266a5d6991e6220",
            "ResourceType": "custom",
            "ResourceOwner": "123456789012"


IpamPoolAllocations -> (list)

The IPAM pool allocations you want information on.


In IPAM, an allocation is a CIDR assignment from an IPAM pool to another IPAM pool or to a resource.

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 . 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.

NextToken -> (string)

The token to use to retrieve the next page of results. This value is null when there are no more results to return.
