I would like to know where I need to call my script so that ifconfig will return the IP address.
Thanks in advance.

if it's running in rc.local, the network should already be configured (being that rc.local is supposed to run after everything else).
If you want it to run at boot time, a slightly more proper way of doing it would be to put your script in /etc/init.d, then link to that script in the correct rcX.d directory (corresponding to your runlevel) with an S99 prefixed to the link name, i.e. S99myscript would be a link to /etc/init.d/myscript.
That said, it *should* work in rc.local. Are you sure paths are correct? It's possible a path var has not been set for the user that runs rc.local scripts (especially for things like /sbin or /usr/local/bin), so include full paths to all programs, i.e. "/sbin/ifconfig" rather than just "ifconfig".
lastly, you could put this in a cron script for your user that compares the output of ifconfig to some file & sends a mail when it changes, though that's kinda kludgey.
