monitoring IP changes

Anybody know a similar program like KEEP ME POSTED?
I wanna see WAN IP changes and to have a report by mail or FTP (best if possible).

Why not just write a script that is run by cron and connects to:
http://checkip.dyndns.org/

I'm not at a linux box right now but something like this should work:

Code:

#!/bin/bash

NEWIP=`lynx -dump http://checkip.dyndns.org | grep "Current IP Address" | cut -d" " -f2`
OLDIP=`cat ~/mylastip`

if [ $NEWIP ne $OLDIP ]; then
echo $NEWIP > ~/mylastip
# Change the next command to a mail command etc if you want the result mailed to you
echo Your ip address has changed from $OLDIP to $NEWIP
fi
