Anyway, typically you wouldn't need to know your IP when doing a
dyndns update. With dns24 for instance, you just
specify "data=client" when you're updating.

What people do is compare the current external IP with what it was the
previous cron job run, and only tell dyndns when it actually changed.

Which is superfluous and a little wasteful.

Consider:

1. check my external IP = one http request
2. if changed, new http request to update

as opposed to:

1. one http request to update. (obviously, the provider knows if any
actual change happened).
