They don't intentionally lie, but the study they are reporting on is uninformed.
"Our research looked at all IPv6 traffic—both native and tunneled, including Teredo, which encapsulates IPv4 traffic in UDP
datagrams using UDP port 3544. We found a peak of only 12 Mbps of Teredo traffic, representing around 10 percent of the
I P protocol 41 traffic."
Teredo uses 3544/UDP to for Client<->Server communication. That is for relay discovery when needed, and the qualification procedure - not much traffic. Client<->Relay communication MAY use 3544/UDP, Client<- >Client communication MAY use 3544/UDP.
In my experience (packets I have been analysing in the last 24 hours for example) suggests that not many actual data packets are on UDP/3544.
I'll get some exact numbers on that in a few hours if you like.
Also that report only includes data up until July 2008. uTorrent with Teredo and IPv6 stuff was released 9 August - which is the intention for my original message.
