Just FYI, if you add a server to your favorites such as "tf2pub.theelders.net" instead of the IP address, Steam resolves the IP address, and does NOT save "tf2pub.theelders.net", so if the IP changes again, you will have to re-add the favorite.
True, but if the IP changes again all they have to do is type in the DNS and it will resolve. Much more convienient then going server list
