Hop Count

Using traceroute and traceroute6, we determined the number of hops between the source node and the destination node. Figs. 2 and 3 show the observed hop counts and its distribution for IPv6/IPv4, with the IPv6 paths having fewer hop counts compared to the IPv4 paths. From our results, the average hop count for IPv4 paths and IPv6 paths is 19.81 hops and 15.22 hops respectively. This may be due to the fact that there are less IPv6 nodes compared to IPv4 nodes in the world. However, compared to previous results, our results do show that the hop count of IPv6 paths has increased. In [1], the average hop counts for IPv4 paths and IPv6 paths were reported to be 17.5 hops and 8.7 hops respectively, while [9] reported 15.75 hops and 9.05 hops for IPv4 paths and IPv6 paths respectively. This comparison indicates that there are more IPv6 nodes deployed in the world now.
