IPv# choice


[link to this post]
 
I've got IPv6 working here, but when I try to reach http://ipv6-speedtest.net/ (referred to by seb here) it reports that I'm using IPv4.

From some reading around, it seems that my browsers (or maybe it's OS X, I'm not sure) will use the IPv4 address rather than the IPv6 one if given the choice- anyone know if it's possible to change this behaviour?

Have you set up an IPv6 over IPv4 tunnel? (Your Internet connection is probably IP4 only - or does your provider support IPv6; and does your router support it?)

ISP is IDNet, router is an Airport Extreme, both support IPv6. The router IPv6 mode is set to "tunnel" if that's what you mean.

The test site I used (http://test-ipv6.com/) says I've got IPv6 connectivity, network prefs reports an IPv6 address and I can access the IPv6-only sites that I've tried. So I think I'm on IPv6...

The test site also makes the comment: Note: Your browser appears to prefer IPv4 over IPv6 when given the choice.

Hence the query.

I read recently that one of the later updates to OS X Snow Leopard switched this preference. It will only connect over IPv6 if IPv4 isn't available. I just Googled it, and found the reference:

Many thanks for that, even if it's not encouraging.

I note the last sentence: There's always hope for 10.6.6... No there isn't frown.

Here's another link that indicates that OS X is the problem.

Cheers... but if I've read it right, it's more of a 6to4 problem than inherently OS X. I'm reasonably sure that IDNet fully support IPv6 so I'll see what they say, and if I can get a genuine v6 connection.

But, from what you say, your router is set to use a 6to4 tunnel - hence the problem.

There's several options, that's just one of them- the others are Host and Router. I don't think Host is appropriate, and when I try Router the IPv6 doesn't work at all (I think I may need to do something in the iMac configuration for that).
