Topic: ext ip dhcp log

[sspfunk]

I have a cable modem to the Internet that is dhcp and it changes every once in a while
is there a log somewhere that would say when the ip changed?
or better yet a script that would email someone when the ip changed

/etc/ppp/ip-up

and enter at before the "exit 0":

echo $4 | mail -s "New IP Myserver" your_desired@
