linux IP watcher

[Lux Zhang]

Hi
my ISP provides a non-statis IP. I am looking for a linux tool to watch ip
address change. that can monitor my public and local IP address. If  IP
address changes it will send an email, to the address specified, with the
new IP address. This email also includes the computer name and time the
change occurred. This is useful for computers that have dynamically assigned
IP addresses, but need to be accessed remotely.


Hope some one can help
