for your regularly scheduled dose of broken ipv6 routing...

And there is of course http://ipv6.nlsde.buaa.edu.cn/ which is sending
nice address range scans trying to spoof proto-41 tunnels and a lot more
nastyness. Of course the owners of the setup are totally unreachable or
simply did not want to respond on why they are spoofing packets.
They do make some funny pictures though, but it mostly maps the 6bone as
that is the information source they used for finding out their tunnels.
Also you have to love the 'paper' on the system with the greatest title
ever: "Dolphin: The Measurement System for the Next Generation Internet"
Of course TTM also has a system for this, but much smarter and with
contactable and actual responding people:
And last but not least:
IPv6 Tunnel Discovery in IPv6
or other words: spoofing proto-41 tunnels for fun and profit.

With the growth of IPv6 research and application, the next generation
Internet is now being widely deployed around the world. This paper
presents an IPv6 Internet measurement system named Dolphin, which
performs the function of network measurement for the IPv6 backbone, as
well as introducing the architecture and realization of the Dolphin
system. In conclusion, it analyzes the topological data of the IPv6
Internet collected by Dolphin, and discusses the future direction of
this measurement work.
