Hey everyone, thanks for all the help! In response to some of your questions about my specifics:

Slackware Linunx
IP Obtained from DHCP server
Reason for needing IP: I am running a streaming Icecast server from my computer (ssshhhhh, don't tell the net admins :), and I want to, everytime I restart, have my computer automagicaly contact a script I write on my webserver, which then updates my page, telling everyone where to connect for my music.

Again, thanks for all the help!
