Ratio of IPv4 and IPv6 hosts

By using a specific trick (collecting IPv6 statistics about clients of some specific web servers), we counted 98 hosts (since midnight UTC):

54 IPv4 only hosts;
33 dual stack hosts where IPv6 is preferred (like Windows XP & Linux) or IPv6 only hosts;
11 dual stack hosts where IPv4 is preferred (like Windows Vista);

Therefore 44.9% of Internet hosts are IPv6 enabled (not counting hosts with IPv6 enabled but without good IPv6 connectivity):

36 host(s) with native IPv6 connectivity;
1 host(s) using 6to4 tunnels (including 1 routers/home gateways);
0 host(s) using ISATAP tunnels;
7 host(s) using Teredo tunnels;
0 Freebox(es).

Statistics about Windows 8 visitors (or do you want any type of addresses, only IPv4 or only IPv6 or only IPv6-preferred or only IPv4-preferred dual-stack or only Freebox IPv6 or only 6to4 IPv6 or only Teredo IPv6 or addresses? Or do you want only Windows XP or Windows Vista or Windows 7 or Windows 8 or Mac OS X or iOS machines?

The last 10 IPv6 accesses Windows 8 visitors

If an IPv4 address is displayed, this means that the host preferred to use IPv4 vs. IPv6; IPv6 is used only when it was explicitely redirected to http://[2001:...]/...
