IP -> e-mail

[Dánielisz László]

Hi everybody,

Let say my computer is connected to the internet with a cable modem and has a dynamic IP address via DHCP. This address is refreshed after every random days.
I want to know the new address even when I'm not home. Like send an e-mail with the new IP, I already know how to do this, but how can I track the event when my computer receives the new IP?
Any ideas or same issues?

Thx!
Laszlo
