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.

As the IPv6 UDP Checksum relaxation effort gets instantiated (the draft
http://tools.ietf.org/html/draft-ietf-6man-udpchecksums-02 is now in
WGLC), could you look at the existence (or lack thereof) of UDP
checksums in IPV6 ? It would be good to have some baseline data to
see, if these become a problem in the future, what the state was
before they were adopted.
