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).
I remember reading at one dynamic IP site that they explicitly asked people not to update the IP if it had not changed, to reduce load on their servers. I don't remember where I read this. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
