Microsoft has offered a Teredo server to allow users behind NAT gateways to obtain an IPv6 connection. Teredo was always considered as a transition technology to obtain IPv6 connectivity is nothing else works to connect to a particular resource ("path of last resort"). With native IPv6 connectivity becoming more common, there will be less need for transition technologies like Teredo.
As we reported earlier, the host name for Microsoft's Teredo server (teredo.ipv6.microsoft.com) doesn't resolve currently. This is appearantly part of a "test" to measure the impact of the service being turned off. As an alternative, Microsoft still offers the "test.ipv6.microsoft.com" hostname to connect to it's Teredo servers. To adjust your settings, use:
netsh interface teredo set state client test.ipv6.microsoft.com
Of course, one may argue that with native IPv6 connecitvity becoming more common, transition technologies like Teredo will be more important for those of us left out in the legacy internet.
