DNS64/NAT64 supports https

Today was the second day I joined APRICOT-APAN2011.  The organizer announced that there was an AP giving IPv6 addresses only and the facility had been equipped with DNS64/NAT64 for crossing to IPv4 networks.   After using it, I was fascinated to note that my IPv6 only Windows 7 laptop could access all IPv4 websites without difficulty.  What's more.  I was able to establish HTTPS connection with IPv4 servers. Here below are two pictures to show the IPv6 addresses and the DNS64 mechanism.  Please click to enlarge when viewing.




In the 2nd screen cap, the IP address of facebook 66.220.147.44 was mapped to 64:ff9b::42dc:932c.  Needless to say 42dc:932c is exactly 66.220.147.44.

Hi,

nice work. I would be glad to know , what is the device which you are using as NAT64. Is that stateful or stateless NAT64 you had configured?. I have seen a lot of documentations regarding NAT64, but it is hard to see a real implementation example.Also how you configure DNS64 in the network.
