is returning the result of IPv4 only now. Any ideas why they would have
rolled back IPv6?

After talking with someone else, i am guessing that your Toredo statement
is correct. However, i don't know why that would have stopped working as
it works fine when i am at school on TWTC circuit. I do not have a Cisco
gateway however, i have been looking into switching to one that i have
