Modern Internet services make significant use of IP Anycast, where multiple locations are identified by the same IP range, and the network distributes traffic across those locations. However, Anycast traffic management is difficult and IPv6 deployments are often less mature than their IPv4 counterparts. This project aimed to build a tool that utilizes publicly available measurement data to identify and correlate changes between IPv4 and IPv6 Anycast routing. We created PATHly Visualizer, a web-based traceroute pathing tool, to visualize paths that packets take from a source probe to Fastly Anycast destinations. PATHly Visualizer allows users to interactively display traceroute data and better understand and evaluate Anycast forwarding in IPv4 and IPv6.
