The majority of DNS resolvers for end users are still run by ISPs and
Telcos. In that paper you reference the only company that can be seen
as an ISP is Level3, although there resolver in contrast to mosts ISPs
is open. The other are the usual open resolver vendors. So this paper
clearly misses a large part of the resolver population.

And my experiences with ISPs and Telkos is that they are, probably
because most of them are regulated very sensitive to privacy and
data analysis for marketing and advertising. A lot of them do or
let others do analytics on their data, mostly after being anonymised,
for security purposes, but not more.

So long
