Well, my ISP and router don't support IPv6 but I discovered Miredo
(Teredo) a while ago. It doesn't seem to work if both ends are using
Teredo behind IPv4 NAT, but other than that it does allow you to connect
to the IPv6 internet.

In Ubuntu (and presumably Debian?) IPv6 support is as easy as 'apt-get
install miredo'. It seems to be made of magic as it sets its self up
automatically in seconds. I've done this on all of my Linux machines now.

With Miredo I got 10/10 and 9/10 because my ISP's DNS server doesn't
support IPv6.


I've just had a couple of emails from Jason Fesler who runs test-ipv6.com, and he says:

Unless you're trying to reach sites that are IPv6-only and have no way to be 
reached via IPv4, I'd consider disabling teredo and miredo.  You're 
intentionally prefering complex setups that can take your packets through 
further routes, and through locations you have nobody to complain to when they 
break.

Is that true? Do teredo/miredo make connections more complicated for IPv4 addresses?

cheers
