Even Micr0$0ft refers to Teredo as "The absolute last resort for IPv6 connectivity". Owen On Sep 11, 2010, at 9:28 AM, Jared Mauch wrote:
I would be careful actually using teredo, as some of them (eg: Microsoft) have swaths of native IPv6 networks that are unreachable.
I'm hoping they will correct some of the problems with it, but it makes IPv6 harder to use for some people as the Microsoft one does not appear to be well supported/connected. I'm not sure if there is an effort under way on Microsofts behalf to correct this, but I hope so.

Does any body maintain a list of Teredo servers and Teredo relays?
A list of public Teredo servers might be useful. But a list of public relays - not so much.
If you google around you'll eventually stumble across the following public servers:
teredo.ipv6.microsoft.com teredo.remlab.net teredo2.remlab.net debian-miredo.progsoc.org teredo.ginzado.ne.jp teredo.iks-jena.de
The first is the default for Windows. The second is the initial default for most Miredo installs. The fourth is supposedly the default for the Debian Miredo package.
You can get an idea of where some public relays might be at:
http://www.bgpmon.net/teredo.php
But there may be a bunch of others not listed. The relay used varies on a per-connection basis. It'll generally be the closest relay to the non-teredo host.
