Re: SlashDot: "Comcast Gunning for NAT Users"

To add more fuel to the fire, how does one combat the issue of "stolen" IP
addresses. Stolen IP's are worse to me than a user doing NAT.

Slightly intuitive users could figure out that their IP is one of a /24 and
just statically assign one to their other machine with out paying for it,
and worse take somebodies IP and make that user non-functional. I know the
cable modem service where I live will allow this type of activity.
