Ratio of IPv4 and IPv6 hosts

Results can be filtered by the web site containing the 'web bug' counting hosts: (you must include the leading http://)
By using a specific trick (collecting IPv6 statistics about clients of some specific web servers), we counted 226 hosts (since midnight UTC):
  • 145 IPv4 only hosts;
  • 47 dual stack hosts where IPv6 is preferred (like Windows XP & Linux) or IPv6 only hosts;
  • 33 dual stack hosts where IPv4 is preferred (like Windows Vista);
Therefore 35.4% of Internet hosts are IPv6 enabled (not counting hosts with IPv6 enabled but without good IPv6 connectivity):
  • 59 host(s) with native IPv6 connectivity;
  • 4 host(s) using 6to4 tunnels (including 4 routers/home gateways);
  • 0 host(s) using ISATAP tunnels;
  • 17 host(s) using Teredo tunnels;
  • 0 Freebox(es).

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:...]/...
