Data shown on this website has three different sources. First, DNS query data is collected using ENTRADA, a tool for analysing very large volumes of DNS data. Also, data has been collected using DMAP, a crawler and classification tool. Both tools are developed by SIDN Labs. Additionally, data is collected by OpenINTEL, a measurement platform to capture daily snapshots of the state of large parts of the global Domain Name System. OpenINTEL is a joint project of the University of Twente, SURF, NLnetLabs, and SIDN Labs.
