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.
