Which region is taking the lead in IPv6
deployment?<http://blog.icann.org/?p=365> September

IPv6 is in the news because the mainstream media have started to pick up the
fact that IPv4 will be fully allocated in the next two or three years. And
IPv6 deployment is important if we want to keep the Internet growing
sustainably.

So where is IPv6 deployment most evident? It's a very difficult thing to
measure. It is difficult to measure the amount of IPv6 traffic as so much of
it is tunneled inside of IPv4. And anyway, tunneled traffic is probably from
end users rather than ISPs, but we need ISPs to deploy IPv6 to allow the
Internet to grow. So how can we see where ISPs are deploying IPv6 in their
networks?

One possible measure of IPv6 deployment in ISPs is the number of IPv6
address blocks (prefixes) seen in the routing table in comparison with the
the number of autonomous systems (ASs - roughly equivalent to ISPs) in a
region. Geoff Huston has a regional breakdown of advertised ASs on his web
site <http://www.potaroo.net/tools/asn32/> and the SixXS project has a
regional breakdown of the IPv6 address blocks visible per region on its web
site <http://www.sixxs.net/tools/grh/dfp/>.

AfriNIC <http://www.afrinic.net/>, the Regional Internet Registry for Africa
and parts of the Indian Ocean, has a higher proportion of networks in its
region announcing IPv6 addresses than the others. Africa also has a smaller
deployed base but IPv6's size is designed to support exactly the kind of
network growth that highly populated areas, like Africa and Asia will see as
their deployed base grows in the next few years.
