RE: some real life data

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

Quite similar to my own web measurements (http://www.vyncke.org/countv6/stats.php) 

IPv6-able (so both when IPv6 is preferred and when it is not)

OS                % of IPv6-able
Windows Vista     57.2
Windows XP        36.4
Linux (unknown)   2.6
Linux (Ubuntu)    1.4
Mac OS X          1.2
Unknown           0.5
Windows CE        0.4
Linux (Debian)    0.2
Windows Server 2  0.2

For Windows Vista: 15% pour Teredo, 9% 6to4 (% relative to the whole Vista population)
For Windows XP: 2% native, 2% Freebox, 0.5% Teredo

This means that more than 1/4 of Windows Vista has IPv6 connectivity which is both a good news and a bad news (meaning that Teredo does not work immediately -- perhaps because they are part of a AD domain or because the firewall has been disabled).
