BGP Route Leaks Analysis

Fri, 6 Mar 2015
A route leak is a violation of the policies between the networks involved. In this project, we obtain routing information from differecent sources and make inferences to detect possible route leaks. These potential route leaks have been further investigated on their duration, the type of violation, and the type and origin of network that caused the leak-detection.

BGP Evolution Analysis

Thu, 31 Jul 2014
The Internet has been growing rapidly for many years. A logical consequence of the growth trend is the increase in effort to discover reachability and routing information of all the networks. The project investigates the different components which together form the actual update message signal and tries to find a reason behind the growth factor.

Measuring the Deployment of DNSSEC over the Internet

Thu, 2 Jul 2014
The deployment of DNSSEC is measured with the RIPE Atlas infrastructure. The results provide new insight on the distribution of DNSSEC support among resolvers, and notably show that around 90% of resolvers are DNSSEC-aware, and about 30% validate answers.
