I now have ATT IPv6 over their residential ADSL broadband. They deployed using 6RD which means every time your IPv4 address changes your IPv6 address changes also. Does anybody have a clue why they chose to use 6RD instead of the much more fully-assed TR-187 for their deployment? Saying they're dimwits doesn't count. Bill

My guess: 6RD pretty readily solves the last-5-miles / provisioning problems - assuming the CPE supports it. Oh, and they expect you to expect your address to change. Out of curiosity - are they giving you a single /64, or something more reasonable / generous? Also OOC - how is the IPv6/6RD throughput & latency, compared to native/NATed IPv4? /TJ
