Teredo: Tunneling IPv6 over UDP through NATs
Bytes: 135228
aka in queue waiting for IANA to act upon it.

Check which has a list of most
/all (send mail if you know more :) public tunnel brokers and all other
related items.

Only AS31701 (Consulintel) and AS5511 (OpenTransit / Wanadoo France) are

But from my logs (including ;) I don't see any
