Comcast and IPv6

[matt-urrlRJtNKRMsHrnhXWJB8w at public.gmane.org (Matt Shields)]

IIRC there was a discussion a week or so ago about IPv6.  It looks like
Comcast is currently running a 6to4 Tunnel for their customers.  I switched
to a new router tonight (Netgear WNDR3700) which with a firmware update had
IPv6 support.  Not knowing what support Comcast had, I changed the setting
to Auto-detect and it detected that they are using 6to4 tunnel.  It
automatically connected to Comcast's network, and it connected to my mac,
and I was able to browse any IPv6 site.

The IP6 options that the Netgear support are Disabled, Auto-detect,
Pass-through, 6to4 Tunnel, Fixed, DHCP and PPPoE
