About Dnsupdate
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is no longer valid.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.

More specifically, the requirements for this program are:

 * Un?x operating system. (e.g. *BSD, Linux, etc.)
   
   
 * Perl >= 5.004 and Net::DNS module.
