| Abstract: | Anycast is mostly used for hosting Domain Name System (DNS) servers, Content Delivery Networks (CDNs), and other purposes, enabling multiple devices to share a single IP address by leveraging the Border Gateway Protocol (BGP) to decide which device to route a packet to. Research exists on how these catchments of Anycast networks form. In this paper, we investigate the impact of IP prefix diversity on network visibility. We want to give insight into the size of discrepancies in the catchment between identical Anycast deployments with different IP addresses. We used Verfploeter (https://dl.acm.org/doi/10.1145/3131365.3131371), a tool to measure catchments of Anycast services, and the TANGLED testbed (https://ieeexplore.ieee.org/document/9463960). To reach our goal, we modified Verfploeter to be able to send requests from multiple source addresses simultaneously. Our results show that 0.5% of the IP addresses we measured responded differently based on the IP prefix we used to reach them. |
