I thought AS5397 said it was a limited test back in Feb 2005?

Hi Daniel,
apologies for not replying to this, but unfortunately Hank did not CC
either our research group or the admins of AS5397, so I did not receive
the email directly, and I am not subscribed to the list.
Those AS-sets do indeed come from us. We announced them because we are
finalizing the document that describes our techniques and we needed
another set of experimental results to confirm their effectiveness.
We know the IPv6 network is not a playground, but we are confident of
the safety of our techniques. This is not only because we have tested
them in the lab on real-world equipment, but also because, as my
original posting said, we tested them in the IPv6 network for several
months and saw no negative effects. Actually, nobody even noticed until
our experiments were almost over.
The document is almost ready and should be available soon, hopefully in
a few days' time.
Regards,
Lorenzo
