Summary: | Nowadays, it is common to find dual-stack services, configured with both IPv4 and IPv6 addresses. However, a service in IPv4 can be viewed and reached by users in a completely different way than its counterpart in IPv6, due to differences in routing policies for these two protocols. Although a challenge on its own, managing a dual-stack service becomes even more challenging when involving anycast: distribution of the service across the Internet by means of deployment of replicas that answer by the same IPv4 and IPv6 addresses. Based on the fact that monitoring tools have for long been strong allies in the management of networks and services in the Internet, in this work we design and implement a supporting tool for visual comparison of IPv4 and IPv6 catchments. The goal of this tool is to help operators understanding how the dynamics of their peering and routing policies impact on the catchment of their anycast service. Using the Root DNS as a case of study, with data collected by RIPE Atlas platform, we validate and demonstrate how the proposed tool supports informed decisions by the service operator. |
