RE: some real life data

["Eric Vyncke (evyncke)" <evyncke@cisco.com>]

Very very interesting because it tends to confirm my own experiment based on http://www.ietf.org/internet-drafts/draft-vyncke-http-server-64aware-00.txt

Also playing tricks with loading an IPv6 only 1x1 pixel images on some web pages. As the web pages are on French speaking web sites until now, there is a clear bias towards France/Canada/Belgium/Switzerland where Free.net has an clear advantage of course.

Stats compiled for more than 1 month:
http://sigma.hec.be/~evyncke/family/countv6/stats.php (see the several graphs at the end)

It is about 10% of IPv6 able clients... (mainly Vista). Teredo is the most used connectivity followed by Free

NB: feel free to look at the http://www.vyncke.org/countv6/ to see how is is done and add the 'tracker' to any page of yours of course.

Empirical experiment with uTorrent also shows between 5% and 10% of IPv6 peers.

Hope this helps to show that IPv6 could be more than the 'advertised' 0.01% of the Internet traffic.
