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?
