[PLUG] Linux, IPv6, and Comcast

[Tim]

Howdy all,

I recently have switched my home line to Comcast and I purchased a
cable modem that supposedly supports ipv6.  In light of world ipv6
day, and the fact that comcast is enabling it for some customers, I
decided to try real quick to get an address with dibbler and a few
other tools, but haven't had any luck.

I don't even know if Comcast has enabled ipv6 in our area or if you
need to opt-in or anything.  Has anyone else tried getting native
dual-stack v6 working in Linux here in the Portland area?
