“Comcast has started IPv6 trials. If Comcast is your ISP, you
can get started using IPv6 on Linux right away, with just a few
simple steps. Ready to join the next-generation network? We’ll show
you how to get Ubuntu 10.10 on Comcast IPv6 in no time.“Anyone on Comcast’s network can participate whether they are
officially in the trial or not. In phase one of their trials they
are relying on the tunneling mechanisms 6to4 and more recently 6RD
(Rapid Deployment). Comcast has “open sourced” its solution based
on OpenWRT if you happen to have a router supported by OpenWRT. I
do not, so like any self-respecting Linux geek, I set out to do it
with a Linux box. I found the documentation for doing so difficult
to find. The 6rd documentation, including the man pages for
iproute2 commands, seems to be missing.“First some background.
