/**
 * Release Address Action Sample
 * The ReleaseAddress operation releases an elastic IP address associated with
 * your account.
 * Note:
 * Releasing an IP address automatically disassociates it from any instance with
 * which it is associated. For more information, see DisassociateAddress.
 * Important:
 * After releasing an elastic IP address, it is released to the IP address pool
 * and might no longer be available to your account. Make sure to update your DNS
 * records and any servers or devices that communicate with the address.
 * If you run this operation on an elastic IP address that is already released,
 * the address might be assigned to another account which will cause Amazon EC2 to
 * return an error.
 *   
 * @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface
 * @param mixed $request Amazon_EC2_Model_ReleaseAddress or array of parameters
