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?

Last week we improved the format of the IANA IPv4 Address Space Registry. It is now much easier to see which address space is available for allocation to RIRs and which address space is reserved for Multicast and Future Use.
We made other changes, too. The IPv4 registry used to report that a lot of /8s were allocated to “Various Registries”. That wasn’t very helpful to anyone; it was a bit like saying “we don’t know”. In fact, the RIRs have been providing DNS and Whois services for addresses in these /8s but the IANA IPv4 registry didn’t indicate which RIR to consult because addresses in each of these /8s are often used by organisations in different RIR regions.

More IPv4 /8s returned to an “IANA – Reserved” status in 2007 then ever before.
With help from the Regional Internet Registries, three /8s were returned in 2007 and last month we recovered one more. We now have 43 unallocated /8s. Here’s a table showing the details of the returned blocks.
