I did this with some of the RIPE folks when I worked at the LINX. The
results (from K, which remember is _only_ authoritative for .) roughly looked
like this:
25% of queries were for '.'
65% of queries were for 'foo.' where foo is NOT a valid TLD
The remaining 10% or so were for GTLD domains, valid TLDs etc.
Also of interest given the RFC1918 debate currently going on was the fact
that 5% of queries originated from 1918 address space.
