Interresting that you say that. Still using 3ffe::/24 and ip6.int I
guess? :) You clearly thought you needed to keep your 'customers'
connected on the 6bone using that block of space.

Yesterday I found in somebody's email the following traceroute:

Yeah, it is alive, 6bone LIVES!!!!! [*] Gee another address-playspace of
a certain someone.

Seriously, some ISP's should finally after more than 2,5 years after
that experiment called 6bone got closed down realize that PEERING over
PAIX which is still using 6bone addresses is quite silly and routing
those addresses is simply not done.

Then again, don't know if Bill can do anything about this one as clearly
the ISPs involved who are still using those addresses are to blame that
they clearly do not care about their network, even though they very well
know from over the years that 6bone was closed down and the address
space returned to IANA. Then again, for those ISPs involved uRPF is also
something hard to understand it seems.

Greets,
 Jeroen
