simple update

Dnsupdate is an IP address update program written in Perl for dynamic DNS updates as defined in RFC2136. This program submits dynamic IP address update requests to a name server automatically.

Dnsupdate gets a current IP address with a simple cgi program (included in this package) which is put on an external HTTP server, and it will send update requests to a name server only if the IP address at the time of the last update is no longer valid.

Dnsupdate can be executed as a daemon which repeatedly updates IP addresses for a domain at a specified interval in the background.

Dnsupdate can add or delete an address record for a domain manually. And it can also add or delete an alias for a domain manually.

Dnsupdate is released under the GNU General Public License.

Requirements

Dnsupdate is written in Perl and uses Net::DNS module.
More specifically, the requirements for this program are:

Un?x operating system. (e.g. *BSD, Linux, etc.)
Perl >= 5.004 and Net::DNS module.
A name server (BIND 8 or later) which allows to update with signed key on the server side.
A HTTP server for the cgi program used to get a current IP Address by dnsupdate outside the host on which dnsupdate runs.
