Hi,

How can I turn on AAAA / IPv6 resolving on a Vista machine thas Teredo IPv6
working?

For example: the Vista machine can visit http://[2001:4860:0:1001::68]/ but
not the normal URL http://ipv6.google.com/

Your name server must support IPv6 lookups. Here's a simple test:

C:\Users\garyd>nslookup
Default Server: ns1.example.com
Address: 10.0.0.25:53

> set type=aaaa
> ipv6.google.com
Server: ns1.example.com
Address: 10.0.0.25:53

Non-authoritative answer:
Name: ipv6.l.google.com
Address: 2001:4860:b002::68
Aliases: ipv6.google.com

My nameserver does support IPv6. It does resolve ipv6.google.com to it's
AAAA address using nslookup.

However, filling out ipv6.google.com in the webbrowser, does not lead to the
google page. Filling out the literal IPv6 address works OK.

So my guess is that the OS has a setting that it should not resolve to IPv6
addresses, possibly to avoid "accidently" IPv6 usage.
I would like to know how to enable IPv6 resolving.

Perhaps it has to do with Teredo as I'm using a tunnel broker. I also use
Firefox but I assume that IE7 under Vista supports IPv6. q.v.

Gary,
Some possibilities:

1.) Check your protocol stack.
Do you have IPV6 listed?
If not add the IPV6 protocol.

Firefox on Vista with the IPV6 protocol added and using a SixXS tunnel
works fine at school on a number of IP V6 sites such as
ipv6.google.com (and others on the ip v6 website list).

2.) Have you checked the latency for your tunnel?
At home using Hughes Satellite Internet, the latency is too long and
IPV6 does not work -- the sites time out using the same SixXS
tunnel.

Regards,
Ed

I think I've found the answer and workaround to your problem:

"In order to avoid 'spamming' the Internet with inefficient and slow IPv6
Teredo traffic, Microsoft have configured DNS so that the system will
_never_ resolve any name to an IPv6 address _as long as_ the system only
has link-local and Teredo IPv6 addresses. Teredo is meant to be used by
applications that specifically request its use and that does not include
any browsers."

With XP SP3, I've found that Teredo does in fact work. Since there are
some BGP routes currently being advertised for Teredo's default IP space,
I was able to get full, albeit slow, access to IPv6 only hosts. I didn't
have to assign a static IP either. I just ran 'ipv6 install,' 'netsh
interface ipv6 set teredo client teredo.ipv6.microsoft.com,' and after a
short pause was able to ping and browse ipv6.google.com using ping -6 and
Firefox 3. I know that Teredo is on by default under Vista but I'm not
sure whether it's trying to reach Microsoft's Teredo server by default. A
'netsh interface ipv6 show teredo' would show you for certain, however.
