DNS-Analysis - Analysis of the DNS root and gTLD nameserver system
This page describes CAIDA activities in Macroscopic DNS Measurements project started in 2001. We conduct both passive and active measurements in order to study the DNS root servers behavior, their connectivity and performance. We also analyze data collected at the servers themselves.
In January 2002 CAIDA began monitoring performance of the DNS root and gTLD nameservers from two NeTraMet monitors based in San Diego and San Jose. After the October 2003 denial of service attack on the root nameservers, CAIDA looked at its DNS performance data to seek better understanding.
