After analyzing the topology data from CAIDA's Scamper and our IPv6 topology discovery system Dolphin, we find that the IPv6 Internet is also scale-free at AS level but with a new feature: its exponent of the degree distribution is just 1.2, which is much smaller than that of the IPv4 Internet network topology.

Based on the IPv6 backbone AS topological data,we improved algorithm for finding community structure in IPv6 network.The fellowing picture is the result.
