And using a relay at Tele2 AB (Sweden).

So really Max, all your outbound IPv6 packets are going via Sweden, even if they're going to elsewhere in the US.

Well, actually, Tele2 has 6to4 relays in Stockholm, Paris, Amsterdam and Frankfurt. But correct, it's a relay in Europe that is being used.

In order to get around this, encourage your ISP to build a 6to4 relay, which is a couple of commands on a spare Cisco router. For extra points, get them to build out a Teredo relay as well, which is a few commands on a spare Linux box.

We have very good experience with 7600 for 6to4 relay usage.

This brings up an interesting question, should we stop announcing our 6to4 relays outside of Europe? Is there consensus in the business how this should be done? I have heard opinions both ways.
