AT&T home DSL IPv6 configuration?

I have some friends and family in various places that have AT&T DSL. At least one has been upgraded to IPv6 support (I connected my notebook to his wireless router and was suprised to see I logged into my server over IPv6). As they tend to ask me for help now and then, I was trying to see how AT&T configured IPv6 for their residential DSL customers, but I can't find anything on their site. They only talk about the routers they sell, and if you don't have one of those, they link to their store to buy one. Can anybody tell me how they are configuring their IPv6 setup? -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
