I'm a fan of Comcast -- namely their total lack of countermeasures aimed at cable modem modification. Unlike some of the Cable ISPs in Europe, they don't: * Make any attempt to fingerprint / forcibly upgrade your firmware * Restrict routing to unauthenticated modem MAC addresses * All they do is give you a walledgarden config * The MAC address database is global and lock-free * The only real authentication is locally in Layer 2 * Ever change the locations/names of their config files
