RFC 2136, RFC 3007
Dynamic DNS Update Tool gives a way to keep domain name pointing to dynamic IP address. It works by sending domain name system update request to name server, which has a zone to be updated. Secure DNS updates are also supported.
The DNS update tool supports only one algorithm - hmac-md5. It's the only proposed algorithm for signing DNS messages.
|address (IP; Default: )||Defines IP address associated with the domain name.|
|dns-server (IP; Default: )||DNS server to send update to.|
|key (string; Default: )||Authorization key to access the server.|
|key-name (string; Default: )||Authorization key name (like a username) to access the server.|
|name (string; Default: )||Name to attach with the IP address.|
|ttl (integer; Default: )||Time to live for the item (in seconds).|
|zone (string; Default: )||DNS zone where to update the domain name in.|
To tell 220.127.116.11 DNS server to (re)associate mydomain name in the myzone.com zone with 18.104.22.168 IP address specifying that the name of the key is dns-update-key and the actual key is update:
