I still keep hoping for some way to buy an ipv6/48 from them. Being
dynamically renumbered all the time is a PITA, and yet, when comcast's
ipv6 works - it is GREAT. I had huge amounts of nat pressure from dns
traffic simply vanish once I switched my dns servers over to their
ipv6 (and deployed dnssec and got back NXDOMAIN)
