release_address

release_address(**kwargs)

Releases the specified Elastic IP address.

[EC2-Classic, default VPC] Releasing an Elastic IP address automatically disassociates it from any instance that it's associated with. To disassociate an Elastic IP address without releasing it, use DisassociateAddress.

Note

We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon Elastic Compute Cloud User Guide .

[Nondefault VPC] You must use DisassociateAddress to disassociate the Elastic IP address before you can release it. Otherwise, Amazon EC2 returns an error ( InvalidIPAddress.InUse ).

After releasing an Elastic IP address, it is released to the IP address pool. Be sure to update your DNS records and any servers or devices that communicate with the address. If you attempt to release an Elastic IP address that you already released, you'll get an AuthFailure error if the address is already allocated to another Amazon Web Services account.

[EC2-VPC] After you release an Elastic IP address for use in a VPC, you might be able to recover it. For more information, see AllocateAddress.

For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide .

Request Syntax

response = client.release_address(
    AllocationId='string',
    PublicIp='string',
    NetworkBorderGroup='string',
    DryRun=True|False
)

Parameters

• AllocationId (string) -- [EC2-VPC] The allocation ID. Required for EC2-VPC.
• PublicIp (string) -- [EC2-Classic] The Elastic IP address. Required for EC2-Classic.
• NetworkBorderGroup (string) --

  The set of Availability Zones, Local Zones, or Wavelength Zones from which Amazon Web Services advertises IP addresses.

  If you provide an incorrect network border group, you receive an InvalidAddress.NotFound error.

  You cannot use a network border group with EC2 Classic. If you attempt this operation on EC2 classic, you receive an InvalidParameterCombination error.

• DryRun (boolean) -- Checks 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 .
