Similar to an experiment done for IPv4 address space, Merit is now performing a darknet experiment with the IPv6 ranges that have been allocated to the RIRs. This also includes prefixes allocated to the RIPE NCC.

16 November 2012: Responding to concerns from IPv6 address space users, we have requested Merit to replace the 2A00::/12 announcement with announcements for currently unallocated address space: 2a04::/14 and 2a08::/13.


Similar to the darknet experiment Merit performed for various IPv4 ranges allocated to the RIRs (see First Impressions of Pollution in Two RIPE NCC Darknets ), MERIT is now performing a darknet experiment for the IPv6 ranges allocated to the RIRs. The RIPE NCC has authorised Merit to temporarily use and announce 2a00::/12 which was allocated to the RIPE NCC by the IANA.

As part of this experiment, MERIT will announce every /12 allocated to each RIR first sequentially and then together. These announcements will each last one week starting on 1 November 2012. You can find more information about this experiment on the Merit web site .

This effort is a follow-up of the work performed by Geoff Huston, Chief Scientist at APNIC for different regions in order to understand any regional variations that might exist (see Traffic in Network and and Traffic in ). The goal is to collect any unwanted traffic in the darknet of the experiment.

Together with MERIT and Geoff Huston, the RIPE NCC will analyse the data and results will be published here on RIPE Labs. We will also have access to the data in case further analysis is warranted.
