RE: one data point regarding native IPv6 support

Oops, copy/paste casualty, sorry. Read below instead.

According to this: http://tinyurl.com/5u3eorn and some
more recent direct talks in French, about half of
worldwide IPv6 traffic is French.

The bulk of it comes from a single ISP (Free, AS12322) and
their IPv6 is 6RD (RFC5569, RFC5969), a variant of 6to4.
Given the constant references in 6RD to 6to4, I will point
out that making 6to4 historic somehow reduces the likeliness
of another extremely successful ISP implementation based on it.

Although Google (in
http://www.pam2010.ethz.ch/papers/full-length/15.pdf) and other
measurements classify AS12322's traffic as native, it is 6RD
behind the scenes.

If the argument is that IPv6 "native" should be the preferred
Solution over "tunneled", it does not hold water. If you were
to remove 6to4 and 6RD from the picture, that would set us back
10 years ago in terms of IPv6 adoption.

Michel.
