The latest CAIDA study says: * The overall query traffic experienced by the roots continues to grow. The observed 2007 query rate and client rate was 1.5-3X above their observed values in 2006 * The proportion of invalid traffic, i.e., DNS pollution, hitting the roots is still high, over 99% of the queries should not even be sent to the root servers. We found an extremely strong correlation both years: the higher the query rate of a client, the lower the fraction of valid queries. That suggests that if the legit traffic increased by an order of magnitude, it would still be down in the noise compared to the junk. Conversely, if root server traffic is an issue, getting networks to clean up their DNS traffic would be much more effective than limiting the number of TLDs. http://www.caida.org/research/dns/roottraffic/comparison06_07.xml R's, John _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
