The new system currently only accepts updates for hosts and not domains as typically nameservers for authorative domains should not change as much as a dynamic host.

The 2 most common/ easiest ways to update your host is either using the dynsite software for win32 (follow the link on the left) - or using wget in a unix environment via cron.

The default syntax for using the auto-update client is:
http://www.fdns.net/updateHostServlet?
USER=test&PASS=test&HOST=myhost&IP=123.123.123.123

-or-

http://www.fdns.net/updateHostServlet?
USER=text&PASS=test&HOST=myhost&IP=*THIS*

If you specify *THIS* as the ip, the system will automatically use whatever address the server is being contacted from for the update. This will work very well for most users such as DSL or CABLE.
