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.
