Which is superfluous and a little wasteful.


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.
