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?
