The current Internet network layer protocol - Internet Protocol
version 4 (IPv4) - has been strained by the rapid growth of the Internet.
Many regions of the world are beginning to transition from IPv4
to Internet Protocol version 6 (IPv6) to support the global need
for a larger number of publicly accessible Internet addresses.
The transition has been underway since 1997,
with the IPv6 Internet coexisting with the IPv4 Internet.
Below, we present a visualization of a sample snapshot of
AS-level IPv6 topology observed during the interval
January 2-8, 2008.
