A Look Inside the Emerging Private IPv4 Market

A significant quantity of unused, previously allocated IPv4 addresses are becoming readily available for re-distribution to IP network operators in need of the depleted addresses. Network World has published a report that takes a look at this emerging private market that's allowing companies with excess numbers to sell them to those in need. 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»

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»

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»

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»

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»

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»

2nd Annual RIPE NCC - LEA meeting: Cooperation Unfolds

On Wednesday 16 March the Serious Organised Crime Agency organised a meeting in London with the RIPE NCC. For the second time law enforcers from the whole world met with the RIPE NCC and RIPE community representatives to discuss cooperation. RIPE NCC staged several very interesting presentations that showed the LEAs the importance of the work done within RIPE and ARIN, the information RIPE NCC has and the relevance of all this to LEAs. Also issues were addressed that can potentially be harmful to future investigations. 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»

IPv6 : Rumours Are More Accurate Than Predictions

As rumours tend to be more accurate than predictions, the last /8's are hanging already on this years Christmas tree and one should hurry to get hold of a small little RIR block to put on next year's tree. I will miss the decade of heated and passionate debates between Tony Hain and Geoff Huston on when the exhaustion would actually happen. Estimates ranged all the way from 2008 to 2020 with Tony predicting early demise of IPv4 addresses while Geoff initially thought exhaustion would come later. As time passed the interval converged and here we are. more»

Internet Continues to Grow at Astonishing Pace (Perspectives from RIPE NCC Membership Stats)

We are at the height of vacation season here in the Netherlands, and the RIPE NCC headquarters in Amsterdam are quieter than usual. The downtime has given me a chance to reflect on how the recent economic downturn has affected our membership growth. The good news is that it hasn't. more»

The IETF's *Other* Diversity Challenge

The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? 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»

What Digital Divide on IP Addresses?

I took an instant dislike to The Digital Divide on IP Addresses post for some reason, well for many reasons actually. First and foremost is that the implication that the "digital divide" is somehow caused by IP address allocation policies. While it is certainly true that there are "digital divides" between developed and developing parts of the world, the historical imbalance in IP addressing is not one of them. The fact is that while we will "run out" of IPv4 addresses at some point in the not too distant future, there are an unimaginably large number of IPv6 addresses available. 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»
