Level Up to IPv6 with Ubuntu 10.10 on Comcast (Linux.com)

FWIW, I've been using the ipv6 service from what I presume is the French ISP in question since it was available, with no issues. DHCP gives ipv4 and ipv6 addresses, as noted. No additional configuration has been required, unless I've forgotten something I did initially. The Ubuntu frontend to iptables, ufw, works fine as well, as do the various network tools I've needed (ping6, tracepath6, etc.)
