More IPv4 Used but Unallocated

by Leo Vegoda on July 30, 2009

Some IPv4 /8s have been used to number IP networks in an unofficial and improper way. That is, they have been used without being properly allocated and registered in a public Whois database. In most cases these networks are mostly private, used internally in their organization, and so the addresses are not seen in the Internet’s routing system. The organizations using these addresses have relied on the overall availability of IPv4 addresses so that there was no pressing need to allocate all of the /8s that IANA manages. With the decreasing IANA free pool of unallocated IPv4 addresses, it is now clear that every last one of them will ultimately be allocated to the RIRs.

Tell us what you think – public comment rundown

by Kieren McCarthy on February 18, 2009

In the build up to every ICANN meeting, there is always a glut of public comment periods as reports are finished in time for the community to review them before discussing them in person.

Mexico City is no exception. Although this time, it is very much easier to get a quick overview of what is out from public comment from the front page of the ICANN website (the third box down on the right). Just to present you with another avenue to finding out about these public comment periods however, there are all listed below with quick explanations of what they are and the dates when they close.

Which region is taking the lead in IPv6 deployment?

by Leo Vegoda on September 28, 2008

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?

Asia-Pacific Registry/Registrar Regional Gathering Concluded

by Craig Schwartz on September 15, 2008

On 10-11 September 2008, ICANN hosted its third Asia/Pacific regional gathering in Seoul, Korea. The regional gathering approach to broadening participation in the ICANN process for gTLD registries and ICANN-accredited registrars was first introduced in February 2005 in Brussels, Belgium. And, since that time, ICANN has conducted annually three outreach events – one each in the Asia/Pacific, Europe and North America regions. As the participation in the community continues to expand to all parts of the world, ICANN anticipates adjusting the model to include other areas such as Latin America/Caribbean Islands, South America, Africa and the Middle East.

Used but Unallocated

by Leo Vegoda on August 4, 2008

In February I commented about how we have been doing some research into the use of unallocated address space on the Internet.

IPv6 was easier than I had expected

by Leo Vegoda on March 12, 2008

Back in October I wrote about how my landlord provides an Internet connection with a private IPv4 address. I explained that I want to connect several devices and so I have installed my own NAT and now sit behind a “double NAT”. The only problems I’ve had have been with some VoIP software that can’t jump multiple NATs.

My landlord isn’t the only ISP providing an Internet connection using private IPv4 addresses. As mentioned at the last AfriNIC meeting, there are many millions of connections sitting behind hierarchies of IPv4 NATs.

No more “Various Registries”

by Leo Vegoda on February 27, 2008

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.

Recovering IPv4 Address Space

by Leo Vegoda on February 6, 2008

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.
