Since early 2015, the University of Twente, SURFnet and SIDN collaborate in the OpenINTEL project. The goal of this project is to perform long-term, large-scale active measurements of the global DNS namespace. Our current coverage is around 60% of the global DNS and included .com, .net, .org, .nl (and other ccTLDs) and most new gTLDs. This talk will explain how we measure at this scale, collecting some 2.2 billion data points per day, and what we can learn about the evolution of the Internet from this data. Examples include adoption of cloud e-mail services and mail security measures, domains crafted for performing DDoS attacks, domains crafted for spam, and many others.
