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.
Current Status
The DNS-ITR project ended on August 31, 2009.
