The number of queries for the '. NS' RRset received at K.root-servers.net today is around 2000/second. This is much higher than what we would expect from well behaved clients. Hence we have studied all priming queries received at K for seven consecutive days in July 2017. This work describes the general characteristics of the priming queries and suggests a classification of client behavior. We will then briefly explore possible strategies for root name servers to improve service to well behaved clients and to support a larger '. NS' RRset.
