IPv6 dark traffic collection restarted

[Geoff Huston <gih () apnic net>]

Hi,

In 2010, and again in 2011, I ran an experiment to examine the "dark" traffic in IPv6. I did this by announcing the 
"superblock" 2400::/12 which has been allocated to APNIC for its IPv6 allocations. The superblock announcement is an 
aggregate and will not disrupt any IPv6 traffic - the packets that will head to this dark traffic collector were on 
their way to /dev/null in any case.

We are about to run this experiment up again to collect a 2012 data profile for IPv6 dark traffic in 2012. Accordingly, 
2400::/12 will be announced by AS3562 - please don't filter it! IPv6 packets are scarce enough already! :-)

This time around we are being assisted by Sandia National Laboratories and ESnet, for which APNIC would like to 
acknowledge their assistance in this ongoing research activity.
