In Beijing Meeting, there were some discussion on how RFC1918 space
was used.

I counted 29 million DNS PTR queries of one of the AS112 servers for
39.5hours in Nov 15-16, 2010 and plot the frequency in each /16 chunk
(Red: 10.0.0.0/8, Green: 172.16.0.0/12, Blue: 192.168.0.0/16).

Asssuming these PTR queries were generated and leaked to the AS112
server based on the real usage, we may conclude that entire space are
in use while degree varies by the address.
