First Broad Internet Census Since 1982 Reveals Surprising Number of Unused IPv4 Addresses

In the upcoming Internet Measurement Conference being held next week in Vouliagmeni, Greece, a team of six researchers will be presenting a paper called "Census and Survey of the Visible Internet," based on a comprehensive census of more 2.8 billion allocated IP addresses on the Internet. The research is claimed to be the first comprehensive census of its kind in more than two decades. more»

IANA: The World Loses if the Technical Industry Checks Out

On Friday, 14 March 2014, the U.S. Department of Commerce National Telecommunications and Information Administration (NTIA) announced its intention to transition the IANA functions to the global multistakeholder community. As expected, the announcement has sent adrenaline coursing through the veins of Internet governance experts and government policy people the world over. I'd argue, however, that it is an important point for the Internet's technical experts to sit up and take notice, as well: the fact that you are probably saying "what problem does this solve?" is a testimony to how much works well today, and we want to make sure it continues to work well in any future arrangements. more»

Breaking It Down: the IANA Transition in Practical Pieces

As a Regional Internet Registry, APNIC has a strong interest in the Internet Assigned Numbers Authority (IANA), and the services it provides. We have followed the progress of IANA carefully, in particular through the evolution of ICANN, and the various steps taken by the US Government to reduce its level of oversight. Along with other RIRs, through the NRO, we have made several public statements about the IANA and its future development, mostly in response to US Government enquiries. more»

Business Case for IPv6 - Part 2

In my previous blog on the topic, I stated that the business case supporting the IPv4 roll-out in the late 90s was the Internet. Although IP depletion will slowly become a reality, the chances are that due to mitigating technologies such as NAT and DNS64, it may take quite a while before organizations in the developed economies will get serious about IPv6. So where should we look to find a business case for IPv6? more»

Simple Overview of ICANN and the IANA Transition by Vint Cerf

Google has released a Doodle Video Animation of its VP and Chief Internet Evangelist, Vint Cerf, explaining inner workings of the Internet, formation of ICANN and the IANA transition. more»

A Closer Look at World IPv6 Day

In observance of World IPv6 Day being held today, Earl Zmijewski of Renesys takes a closer look at the state of the IPv6 today. Zmijewski writes: "Today is World IPv6 Day, a day when major content providers have agreed to furnish service over IPv6 for a 24-hour test period. Hopefully, you didn't notice anything different about your Internet experience today, but providers will have gained valuable experience with the technology and any technical hurdles that remain to be overcome..." more»

IPv4 Address Space Now Below 5%, Says NRO

The Number Resource Organization (NRO) announced today that less than five percent of the world's IPv4 addresses remain unallocated. APNIC, the Regional Internet Registry for the Asia Pacific region, has been assigned two blocks of IPv4 addresses by the Internet Assigned Numbers Authority (IANA). This latest allocation means that the IPv4 free pool dipped below 10% in January, just nine months ago. Since then, over 200 million IPv4 addresses have been allocated from IANA to the Regional Internet Registries (RIRs). more»

RIPE NCC Distributed Last IPv4 Address Space from the Available Pool

On Friday 14 September, 2012, the RIPE NCC, the Regional Internet Registry (RIR) for Europe, the Middle East and parts of Central Asia, distributed the last blocks of IPv4 address space from the available pool. more»

IPv6 Momentum?

Last month, the Obama administration sponsored one of the first high-level government workshops on IPv6. At the meeting, the administration's Chief Information Officer, Vivek Kundra, announced a remarkable 2012 deadline for federal agencies to support IPv6. So with a high-level US government mandate and a recent spade of vendor and carrier IPv6 announcements (e.g. VeriSign, Hurricane Electric), is the 15 year old IPv6 migration effort finally gaining momentum? more»

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more»

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more»

ARIN Launches WHOWAS: Trial Service Providing Historical Information for a Given IP Address

American Registry for Internet Numbers (ARIN) is running a trial service that gives users access to historical IP whois data – that is, it will tell you who was responsible for an IP address or block of IPs. The service is not automated and if you want to access it you will need to submit a request via email with information about not only what you want to know, but why you are interested in accessing the information. more»

Business Case for IPv6 - Part 1

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. more»

Google Officially Announces Introduction of IPv6

Google search is available over IPv6 at ipv6.google.com (you'll need an IPv6 connection to view it)... From the official blog: "We hope that by allowing every computer and mobile device on the network to talk to each other directly -- an idea known as the "end-to-end principle" that was crucial to the original design of the Internet -- IPv6 will allow the continued growth of the Internet and enable new applications yet to be invented." more»

The Central IPv4 Pool is Gone

Yesterday, the Asia-Pacific registry got the last two blocks in the central IPv4 pool. The IANA has been sitting on five /8s (one per regional registry), and these will be handed out (along with the fragments from the legacy class B space), one to each registry. The IANA IPv4 registry doesn't yet reflect this. more»
