-- | Registers an Elastic IP address with a specified stack. An address can be
-- registered with only one stack at a time. If the address is already
-- registered, you must first deregister it by calling 'DeregisterElasticIp'. For
-- more information, see <http://docs.aws.amazon.com/opsworks/latest/userguide/resources.html Resource Management>.
--
-- Required Permissions: To use this action, an IAM user must have a Manage
-- permissions level for the stack, or an attached policy that explicitly grants
-- permissions. For more information on user permissions, see <http://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html Managing UserPermissions>.
