windows 7 didn't do aaaa record lookup

My laptop is installed with Windows 7 SP1 Ultimate , 64 bit version.

Recently, I went to the university, which only provides ipv6.

I've built a OpenVPN Tunnel to handle ipv4 traffic, but I've found when I enable OpenVPN Tunnel, all domain with ipv6 only will failed but numeric address (like 2001:a:b::c) works.

I've tried microsoft fix me 50441, which change settings to prefer ipv6 over ipv4, doesn't work. nor does changing the priority of ipv6 prefixpolicies(change ::ffff:0:0/96 to the lowest).

When I use wireshark to monitor my traffic, I've found that my laptop did only A record lookup instead of AAAA record. How could I fix it?

EDIT: I've added some information which may be useful for find out the problem.

It's likely that IPv4 is Windows' preferred choice over IPv6.

Network and Sharing center -> Change adapter settings -> Advanced menu -> Advanced settings

At the bottom of this form move IPv6 above IPv4 and it should have the preference. – Adambean – 2013-02-22T21:15:34.717

@Adambean Thanks for your comment. I have tried your solution, it works! – Yifu Yu – 2013-02-23T02:52:06.777

@Adambean Yes, you should post this as an answer. – Michael Hampton – 2013-02-23T04:04:27.360

Hi Mike, glad to here it worked out. I wasn't sure if it would work so I didn't post it as an answer. Have done now :) – Adambean – 2013-02-23T13:46:14.390
