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?


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?
