That's only one part of the answer: public relays, or relays in the
network you're visiting. There could be hundreds of relays out there.
The only way to measure that would be to run some logging on a 6to4 router
-- check which addresses packets tunneled to come from 2001/3ffe come from
(and take out the spoofs).

You're sitting in a wrong network :-). Try e.g. from somewhere Abilene.
