Yep, Comcast ties your modem's mac address to an IP address.
However, if your modem is off long enough for a new user in your area to need a new IP address, they'll snatch up yours.
Also, 10 years? I guess DOCSIS 3.0 has been around that long. That's pretty impressive.
- ktm5j 6y agoI recently got a docsis 3.1 modem, you have to call and activate the MAC. They just used the same IP, conveniently enough.
- proverbialbunny 6y agoIt's probably because it needed an IP and the modem that was turned off, leaving an IP open was your old one. That or they changed their system. The odds historically have been low getting the same IP.
