If a default already exists, this overwrites it.  |\n| internal  |                  | Forces the given suffix to use private IPs                                                    |\n| mdns      |                  | Activates multicast DNS support for the given suffix                                           |\n| slaves    | list of IPv4 addresses | The given suffix will notify the frontend DNS servers when a change in the frontend DNS has occurred |\n| use_aaaa_ns |                | Activates IPv6 address support |\n\n### Returns\n\nReturns `Added suffixes successfully` if the suffix was added. Otherwise, it returns an error.\n\n### Example\n\n``` sh\n$ rladmin suffix add name new.rediscluster.local\nAdded suffixes successfully\n```\n\n## `suffix delete`\n\nDeletes an existing DNS suffix from the cluster.\n\n``` sh\nrladmin suffix delete name \u003cname\u003e\n```\n\n### Parameters\n\n| Parameter | Type/Value       | Description                                                                                   |\n|-----------|------------------|-----------------------------------------------------------------------------------------------|\n| name      | string           | DNS suffix to delete from the cluster                                                         |\n\n### Returns\n\nReturns `Suffix deleted successfully` if the suffix was deleted. Otherwise, it returns an error.\n\n### Example\n\n``` sh\n$ rladmin suffix delete name new.rediscluster.local\nSuffix deleted successfully\n```\n\n## `suffix list`\n\nLists the DNS suffixes in the cluster.\n\n```sh\nrladmin suffix list\n```\n\n### Parameters\n\nNone\n\n### Returns\n\nReturns a list of the DNS suffixes.\n\n### Example\n\n``` sh\n$ rladmin suffix list\nList of all suffixes:\ncluster.local\nnew.rediscluster.local\n```\n",
