DNS-Analysis - Analysis of the DNS root and gTLD nameserver system
This page describes CAIDA and related 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 the vantage point of two NeTraMet monitors located in San Diego and San Jose. In the aftermath of the unusual denial of service (DoS) attack on the root nameservers reported by the Associated Press on October 23, CAIDA looked at its DNS performance data to provide some context and seek better understanding.
