Hi,

Using Vista and the built-in Teredo, I can access sites like
http://[2001:4860:0:1001::68]/ and http://[2001:610:510:0:192:42:113:60]/

However, I can *not* access them using their normal URLs
http://ipv6.google.com/ and http://www.ipv6.surfnet.nl/

Same is true for tracert6 and ping6: literals work, names not.

I would expect from teredo that IPv6-only URLs like http://ipv6.google.com/
would work. Apparently not.

How can I make http://ipv6.google.com/ work?

de Kameel,
I am an IPV6 newbie.

I am using Windows Vista Enterprise with IP6 enabled. When using the
SW supplied through www.SixXS.net/main and a tunnel supplied by them,
to uslax01.sixxs.net, the IP6 websites like ipv6.google.com work just
fine, automatically.

I am assuming that the thing you might need is an IPV6 DNS that
translates your IPV6 urls into IPV6 addresses (and/or an IPV6 DHCP.

I am interested in how you solve this and how I can get a list of IPV6
URLs of interest.

Do you know of a simple test of whether a URL is IPV4 or IPV6 rather
than relying on the system to do so?

Thanks for your help.

You can install the plugin ShowIP in Firefox: it will show the IPv6 or IPv4
address in the right lower bar.

See https://addons.mozilla.org/en-US/firefox/addon/590

Thanks for the suggestion.
On installing, I am told that the extension is not compatible with
Firefox 3.0.5.
Rats!!

Which just does an AAAA and then A lookup, which doesn't actually mean
that one is really connecting to the site over IPv6 or IPv4, it only
indicates that one _could_ connect to it over the indicated protocol.

In short: very futile extension.

They would have to install this much lower inside the network stack of
Firefox for it to actually work.

Greets,
Jeroen

Which is *exactly* what Edward asked for: "whether a URL is IPV4 or IPV6".

Edward was *not* asking if the connection itself was over IPv4 or IPv6.
