Vulnerability Development: Re: Hijack IP Address using cable modem

[Bill Munger <bmunger () LIGHTSHIPMAIL NET>]

Interesting thing about the AT&T / roadrunner cable network is that the
DNS name for your IP contains your MAC address. If they do in fact use
it as some kind of authorization (which seems likely enough, as I have
had to call them with my MAC address after getting a new NIC), then they
sure don't trouble themselves about keeping it a secret. And it is
possible to change your MAC in software for some NICs.
