DNS-ITR Project
CAIDA DNS-ITR project "Improving the Integrity of Domain Name System (DNS) Monitoring and Protection" (NSF grant SCI-0427144) started in 2004 and concluded in 2009. Our primary objective was to provide much needed data in support of the DNS research. The data collection and analysis methods, services and tools resulting from this project are essential to protecting the robustness and advancing the development of the global Internet.

Funding Source: NSF 0427144. Period of performance: September 15, 2004 - August 31, 2009.
