- Description:
- DNS is one of the cornerstones of the Internet. Nowadays, a substantial fraction of DNS queries are handled by public resolvers (e.g., Google Public DNS and Cisco’s OpenDNS) rather than ISP nameservers. This behavior makes it difficult for authoritative nameservers to provide answers based on the requesting resolver. The impact is especially important for entities that make client origin inferences to perform DNS-based load balancing (e.g., CDNS). The EDNS0 Client Subnet (ECS) option adds the client’s IP prefix to DNS queries, which allows authoritative nameservers to provide prefix-based responses. Previous work showed the potential of data collected during ECS scans. Infrastructure can be uncovered and subnet specific behavior of operators can be observed. In the study "ECSeptional DNS Data: Evaluating Nameserver ECS Deployments with Response-Aware Scanning", we introduce a new method for conducting ECS scans, which provides insights into ECS behavior and significantly reduces the required number of queries by up to 97 % compared to state-of-the-art techniques. This dataset includes scan results used in the evaluation of our paper.
- Method of data assessment:
- We used our ECS scanner ECSplorer [1] to obtain all data within this dataset. Find more instructions on how to use the scanner inside its description. [1] https://github.com/tumi8/ecsplorer
