As mentioned there it is *not* in the specs, tunneling can be done by most
of them, especially as this is merely a bridge, but unfortunately most DOCSIS's
apparently don't do it per default the correct way thus you won't get native IPv6,
but then again, your ISP also needs to provide it too you...

People saying they have IPv6 at comcast either are using some very
unknown beta service or are simply using 6to4, which should simply
'work' when you type 'ipv6 install' on an XP box, given that it might
also do Teredo if 6to4 fails.
