// 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. We are retiring EC2-Classic on August 15, 2022. We
// recommend that you migrate from EC2-Classic to a VPC. For more information, see
// Migrate from EC2-Classic to a VPC
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-migrate.html) 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
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html)
// in the Amazon Elastic Compute Cloud User Guide.
