Several well-known measurement studies have revealed aspects of the Internet's AS-level and router-level topologies, and derived a few important properties. This has yielded graph models and parameter ranges that allow for greater confidence in simulation of new protocols as well as a deeper understanding of the Internet's structure and similarity to other types of technological, biological, economic, and social networks. The majority of Internet topology studies have been focused on the IPv4 portion of the Internet, and at this time relatively few observations of the Internet's IPv6 topology have been published. In this report, we use over three years of data gathered in the Route Views archives to describe some basic properties of the IPv6 AS-level topology. We find similarities with the IPv4 AS graph in several regards, including the small-world nature of the graph. We also find some interesting differences, including the values of the graph's diameter and the criticality of a few well-connected nodes.
