The Internet Service Provider (ISP) community is carefully watching the impending depletion of the unassigned IPv4 address pool. Most estimates place the depletion of the central pool of unassigned IPv4 addresses by mid-2011. After that, each Regional Internet Registry (RIR) will continue to satisfy requests for additional IPv4 space for a limited time (depending on the rate of incoming requests and the amount of address space on hand in the RIR at the time of central pool depletion). more
The 7th African Peering and Interconnection Forum (AfPIF) took place in Dar es Salaam, Tanzania, from 30 August - 1 September 2016. AfPIF is the annual conference organised by the Internet Society to specifically address interconnection challenges together with the wide-ranging opportunities the African continent offers. Tanzania is well-known for its safari, Mount Kilimanjaro and beautiful Zanzibar beaches, but not only that... more
I bet that nobody believed in 1992 that thirty years later, we'd still be discussing the state of the transition to IPv6! In 1992 we were discussing what to do about the forthcoming address crunch in IPv4, and having come to terms with the inevitable prospect that the silicon industry was going to outpace the capacity of the IPv4 address pool in a couple of years, we needed to do something quickly more
The Australian Domain Name Administration, AUDA, recently published its quarterly report for the last quarter of 2020. The report contained the interesting snippet: "The rapid digitization of our lives and economy -- necessitated by COVID-19 -- continued to underpin strong growth in .au registrations. New .au domains created in December 2020 were up 23 percent from December 2019, while total domains under management were up more than 2.1 percent over the same period." more
This year, we expect that the RIPE NCC's pool of unallocated IPv4 addresses will reach the "last /8", meaning that we have 16,777,216 IPv4 addresses left in the available pool. At that point it will no longer be possible for RIPE NCC members to obtain the amount of IPv4 addresses they will require to expand their current and future networks. When we hit the last /8, the RIPE NCC will only be able to distribute IPv6 addresses and a one-off allocation of IPv4 address space... Has this caused a last minute rush? more
In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more
Sustainability is a difficult term to avoid these days. With that in mind, it's somewhat surprising that last week's European Dialogue on Internet Governance (EuroDIG), now in its tenth year, featured one of its first workshops looking at the subject. But while the workshop focused on issues of energy usage and e-waste, the concept of sustainability raises some much broader and likely difficult questions for the Internet governance community. more
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
At the IETF 95 meeting at the start of April, I was in a meeting of the IPv4 Sunset Working Group, and heard Lee Howard, Director of Network Technology at Time Warner Cable, present on a proposal that recommended that IP version 4, or to be specific, that the technical protocol specification documented in RFC 791, be declared "Historic"... The rationale for this proposed re-designation of IPv4 was that this protocol has indeed been superseded by a more recent specification, namely IP version 6. more
The IPv4 market has grown significantly in the last four years. It finished particularly strong in 2017, both in terms of the total volume of addresses traded and overall number of intra- and inter-RIR transactions in the ARIN region. Over the last four years, the steady and sometimes substantial growth in the number of transactions has been mostly attributable to a dramatic increase in small block trades of fewer than 4,000 addresses. more
It's no secret that the supply of IPv4 addresses, on which the Internet has been based since the dawn of digital time, is rapidly running out. The official replacement is much larger IPv6 addresses, but I can report from experience that the task of switching is not trivial, and for a long time there will be a lot of the net that's only on IPv4. So once the initial supply of IPv4 addresses run out, and the only way to get some is to buy them from someone else, what will the market be like? more
It's January again, and being the start of another year, it's as good a time as any to look at the last 12 months and see what the Internet was up to in 2010. This is an update to the report prepared 12 months ago when looking at 2009, so lets see what has changed in the past 12 months in addressing the Internet, and look at how address allocation information can inform us of the changing nature of the network itself. more
Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. more
Two weeks before depletion of the American Registry for Internet Numbers (ARIN) IPv4 free pool in September 2015, we published an article recommending that the ARIN community adopt transfer policies that encourage trading transparency and improve whois registry accuracy. By eliminating needs justification as a pre-condition to updating the registry, we argued that ARIN could eliminate existing policy-based barriers that have kept many otherwise lawful and legitimate commercial transactions in the shadows. more
World IPv6 Launch kicked off 6 June 2012 at 00:00 UTC. On this day, multitudes of website operators, network operators and home router vendors from all over the world have joined thousands of companies and millions of websites in permanently enabling the next generation Internet. They have done this by turning IPv6 support on by default in (at least some of) their products and services. This is a major milestone in the history of the Internet. more
