Not in the least. For all their atrocities, Comcast was one of the early IPv6 adopters and has rolled it out to their entire residential customer base (people with older modems/routers that don't support IPv6 obviously won't pull an IPv6 IP address). That's EASILY 11% of US internet traffic.

Just curious, do the internal interfaces on Comcast's IPv6 routers give out V4 or V6 addresses?

I think that's the point I was trying to make.
