I just set up a HE tunnel on my Windows 7 PC, and while i can browse to http://[2a01:3f0:0:a::186]/ i cannot browse to http://ipv6only.bredbandskollen.se which is their FQDN. Also, the speedtest flash doesnt load as its probably trying to do a lookup of an ipv6 address to pull its data.

My DNS servers are set to 8.8.8.8 and 8.8.4.4. If i do:

nslookup nslookup -type=aaaa ipv6.bredbandskollen.se 8.8.8.8

i get a this response:

Server:  google-public-dns-a.google.com
Address:  8.8.8.8

*** Inga IPv6 address-poster (AAAA) är tillgängliga för ipv6.bredbandskollen.se

Translated to english that basically means that there are no ipv6-posts (aaaa) available for that domain.

says:

IPv6 connections work, but connections using DNS names do not use IPv6. For some reason, your browser or your OS is not doing IPv6 DNS 'AAAA' lookups.

Here is my ipconfig:

And this are the commands used to set up the tunnel

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 12.207.*.* 216.66.80.26
netsh interface ipv6 add address IP6Tunnel 2001:470:*:*::*
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:*:*::*

I checked network.dns.disableIPv6 in about:config in the Firefox 4 that i use and it was false. What more could be wrong? –  Maciej Swic May 21 '11 at 16:02

Might be a fluke - some DNS problems go away themself.

It works here:

Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    ipv6.bredbandskollen.se
Address:  2a01:3f0:0:a::186

The again, 8.8.8.8 might be more than one server, so while mine is working, yours might have a problem.

Another problem: Sometimes people do filter DNS packages. The filter might not know about AAAA records yet. Your DNS suffix (Hilton.com) implies that such filtering is possible.

If your IPv6 tunnel is up, try one of the OpenDNS IPv6 DNS servers:

nslookup -type=aaaa ipv6.bredbandskollen.se 2620:0:ccc::2

Running that OpendDNS query returned a pretty interesting answer: C:\Users\Maciej Swic>nslookup -type=aaaa ipv6.bredbandskollen.se 2620:0:ccc::2 DNS request timed out. timeout was 2 seconds. Server: UnKnown Address: 2620:0:ccc::2 Non-authoritative answer: Namn: ipv6.bredbandskollen.se Address: 2a01:3f0:0:a::186 –  Maciej Swic May 21 '11 at 18:32
    
So it both timed out and i got an answer. And as mentioned before the tunnel is up, i can go to http://[ipv6-addr], just cant to lookups. –  Maciej Swic May 21 '11 at 18:34
    
I get this too, seems like reverse loopkup is not set up for this address. –  Turbo J May 21 '11 at 18:37
    
Upon adding 2620:0:ccc::2 and 2620:0:ccd::2 to my DNS servers, i can now go to ipv6only.bredbandskollen.se and the flash loads. Very strange Google wont return AAAA records but i guess its their fault then... –  Maciej Swic May 21 '11 at 18:37
