Ratio of IPv4 and IPv6 hosts

By using a specific trick (collecting IPv6 statistics about clients of some specific web servers), we counted 138 hosts (since midnight UTC):

87 IPv4 only hosts;
38 dual stack hosts where IPv6 is preferred (like Windows XP & Linux) or IPv6 only hosts;
13 dual stack hosts where IPv4 is preferred (like Windows Vista);

Therefore 36.96% of Internet hosts are IPv6 enabled (not counting hosts with IPv6 enabled but without good IPv6 connectivity):

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

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:...]/...
