Description
The past analysis reported numbers of queries sent from each address
to root DNS servers. There are 30,000 IP addresses which send over
100,000 queries in 48 hours. 100,000 queries per 48 hours seem to be
too much. However, a full-resolver managed appropriately sent 110,000
queries in 48 hours at 2012 DITL timing. It served 180 queries per
second from thousands of clients. The author replayed the 48 hours client
queries to BIND 9 and Unbound full-resolvers, and compared number of
queries to root DNS servers and other authorititative DNS servers.
