I use ddts (http://www.ddts.org/) and there's a debian package
that polls the central server every minute and update the ip
when it polls. So when i install that client i only need to
open the appropriate port and my ip is updated every minute.
Your DNS service might (and probably does) have such a script
to do this.
Why not run it every x minute(s) instead of only when the ip changes?
It doesn't take a lot of bandwidth or cpu time to do so.
You can probably make a cron job out of it too.
