Your router's MAC address is stored in Comcast's ARP (Address Resolution Protocol) tables for a set amount of time (most likely a few hours, I think). If you unplug the router and wait until you fall out of the ARP table, then it will decide you're not there any more and give the IP to someone else if they request one. Otherwise, your IP address will probably stay the same.
