They don't have "IPv6 enabled web systems", a lot of people wished that they did. What your problem most likely was, was a broken DNS server, which, when queried for an AAAA simply doesn't respond. Most Network Operators (to keep it a bit on topic for this mailinglist) can't do anything about broken DNS servers at End User sites. Note that this has *nothing* to do with Teredo, which even doesn't activate itself when it can't get packets to be relayed. You can't thus blame Microsoft for this. The DNS server is broken, not them. I know it is always fun to blame M$ but really it isn't true. Note also that the BBC once did have a AAAA related DNS problem, that was in 2002 though and was quickly resolved: http://www.merit.edu/mail.archives/nanog/2002-04/msg00559.html These had another kind of problem, they returned NXDOMAIN, so that it looked like the requested label was not there; much better still than the simple ignore and forget of the End User DNS problems. > I was once, circa 1995 or so, fairly enamored of IPv6.

Enough to provide our children's children children and the rest of the world with unique addressable address space.

As it primarily resolves the address space problem and it solves this perfectly well, how exactly did your world move on by staying limited to 32bits and only 4 million addresses while there are many more people on this planet, not even thinking of subnets or having multiple addresses per person?
