Up here in Comcast territory, you have to register your router's (or
computer NIC's) MAC address with the company before you will be allowed
through the network.  (I think you get an IP address from the DHCP server,
but your packets are blocked from going anywhere.)

So if/when you get a new router, or change its MAC address, you have to 
call them up and let them know.  I guess this is done to discourage 
nefariousness, but it still seems like a lot of hassle for them, and a lot 
of call center expenses.

So just remember - it can get a lot worse than TWC!
