DNS Traffic of a Tor Exit Node - An Analysis

Abstract

The DNS traffic of a large-bandwidth Tor exit node is investigated for anomalies and compared to domain name registrations. From the results we can conclude what people are using the Tor network for. Some national anomalies can be identified - websites in China (.cn) and Russia (.ru/.su), and to some degree in Ukraine (.ua), are used differently through Tor than e.g. websites under the top-level domain of Germany (.de).
