Ah, finally something I know a little something about. OCT uses wireless connections to give your complex access. These come from one of three directional antennas up near the Y on the mountain. Once inside the complex they use Linux boxen as routers. They do this because when your computer asks for an IP address, they check your MAC address against a database of subscribers. From the DB they can either grant or deny access, determine throttling, and give you an IP from a few different pools. This IP will be in one of three possible pools: 1) 10.2.x.x if you don't have an account, 2) 10.1.x.x if you have an account but don't pay the extra $6/mo for a public IP, and 3) 208.187.x.x if you have an account and do pay for a static IP.
The 10.2.x.x addresses are automatically forwarded to the web servers that handle new user sign-ups whenever they request any web page. The 10.1.x.x addresses can see the world through port-blocked lenses. About all that gets through is HTTP, FTP, SSH, and a couple other things. The 208.187.x.x addresses don't have any ports blocked and are quite nice for things like SSHing into your box from school. The line from the router to your apartment could be any of a number of things. In my building they run something called HPNA that acts like ethernet through the phone lines. They give us a box that plugs into the regular phone jack and has an ethernet port on the side. To find out what IP address you've been assigned, try /sbin/ifconfig.
