Nowadays, a substantial<br>fraction of DNS queries are handled by public resolvers (e.g., Google Public<br>DNS and Cisco's OpenDNS) rather than ISP nameservers. This behavior makes it<br>difficult for authoritative nameservers to provide answers based on the<br>requesting resolver. The impact is especially important for entities that make<br>client origin inferences to perform DNS-based load balancing (e.g., CDNS). The<br>EDNS0 Client Subnet (ECS) option adds the client's IP prefix to DNS queries,<br>which allows authoritative nameservers to provide prefix-based responses. In<br>this study, we introduce a new method for conducting ECS scans, which provides<br>insights into ECS behavior and significantly reduces the required number of<br>queries by up to 97% compared to state-of-the-art techniques. Our approach is<br>also the first to facilitate ECS scans for IPv6. We conduct a comprehensive<br>evaluation of the ECS landscape, examining the usage and implementation of ECS<br>across various services. Overall, 53% of all nameservers support prefix-based<br>responses. Furthermore, we find that Google nameservers do not comply with the<br>Google Public DNS guidelines. Lastly, we plan to make our tool, and data<br>publicly available to foster further research in the area.<br> %K Computer Science, Networking and Internet Architecture, cs.NI
