Thanks everyone for the input.

What is described here is consistent with my experience with cable modems in 
NC.  The cable modem itself attaches to a MAC address, and likewise an IP 
address is held for that MAC address.  If you want to connect a different 
device to the cable modem you can:

1. Power cycle the cable modem, resulting in a new IP
2. Spoof the MAC address on the new device to match the old, retaining the old 
IP.
