Abstract

IP anycast is extensively used to distribute services in the Internet. It relies on BGP, which makes management complex. Furthermore, the availability of such services in IPv4 and IPv6 (dual stack) increases management complexity. In this paper we introduce CatchmentView, a visualization tool that builds graphics of routes using traceroute data from measurement sources to anycast sites. Visualization from CatchmentView helps operators identifying differences between routing and catchment of anycast dual stack services. We built CatchmentView based on the Root DNS servers that are dual stack and leverage anycast for distribution. Using traceroutedata from RIPE Atlas we validate CatchmentView.
