Scarcity of IPv4 Addresses

My friend Kurtis writes in his blog some points he has been thinking of while discussing "when we run out of IPv4 addresses". In reality, as he points out so well, we will not run out. It will be harder to get addresses. It is also the case that unfortunately people that push for IPv6 claim IPv6 will solve all different kinds of problem. Possibly also the starvation problems in the world... more

The End of the (IPv4) World is Nigher!

Funny how some topics seem sit on a quiet back burner for years, and then all of a sudden become matters of relatively intense attention. Over the past few weeks we've seen a number of pronouncements on the imminent exhaustion of the IP version 4 address pools. Not only have some of the Regional Internet Registries (RIRs) and some national registry bodies made public statements on the topic, we've now seen ICANN also make its pronouncement on this topic... Why the sudden uptake of interest in this topic? I suspect that a small part of this may be my fault! more

What Prevents IPv6 Deployment in Europe

ZDNet UK has an article on IPv6 and what may slow down its deployment. Jay Daley, from Nominet points out to the fact that the current IPv6 allocation policy used by RIPE NCC is geared towards ISPs. This is a complaint I have heard time and time again. Under the current policy, you have to show to RIPE NCC that you are going to allocate 200 address blocks to your customers before you are allocated a /32 block. Obviously, a large corporate network cannot afford to renumber every time it switches ISPs... more

More IPv6 Warnings on Why Organizations Must Plan Transition Now

The IPv6 Portal reports on a paper titled "The Choice: IPV4 Exhaustion or Transition to IPv6", written by Jordi Palet, warning that organizations must start planning for IPv6 now or "be aware that some already have, and you are beginning to be at a disadvantage." From the report: "This is going to affect the business of existing Internet Service Providers (ISPs) and to a greater extent, at a certain point in time, the creation of new ISPs. As a consequence if may have a deeper impact in developing regions (Africa, Asia and Latin America/Caribbean) where the penetration of the Internet is not yet so widespread." more

ARIN Provides Latest Word on Need to Move to IPv6: Will Anyone Heed the Warning? (Does anyone care?)

NetworkWorld is running an article today that talks about the announcement from ARIN (the American Registry for Internet Numbers) of the ARIN Board resolution calling upon ARIN to no longer be "neutral" in the IPv4 vs IPv6 space and instead work to actively encourage migration to IPv6... Until now, ARIN and the other RIRs have generally been fairly neutral in the IPv4 versus IPv6 debate and have not shown a preference in allocation, but this announcement from ARIN shows the first signs of change. more

IPv6 for the Rest of Us

IPv6 deployment is in a chicken and egg situation. On the one hand, there is no willingness from ISPs and commodity DNS router manufacturers to include IPv6 support in their infrastructure or equipment because "there is no demand". On the other hand, there is no demand because the average Joe Blow could not care less if he accesses a web site under IPv4 or IPv6. It should just work. The equipment and infrastructure should adapt transparently... What we users can do is to stop waiting for the industry to get its act together and work around its limitations... more

Are We Slowly Losing Control of the Internet?

I have long been intrigued by the question of how do we turn the internet into a lifeline grade infrastructure... My hope that this will occur soon or even within decades is diminishing. Most of us observe, almost daily, how even well established infrastructures tend to crumble when stressed, even slightly... I was at the O'Reilly Etel conference last week. The content was impressive and the people there were frequently the primary actors in the creation and deployment of VOIP. However, not once during the three days did I hear a serious discussion by a speaker or in the hallways about how this evolving system would be managed, monitored, diagnosed, or repaired. more

Addressing the Future Internet

What economic and social factors are shaping our future needs and expectations for communications systems? This question was the theme of a joint National Science Foundation (NSF) and Organisation for Economic Co Operation and Development (OECD) workshop, held on the 31st January of this year. The approach taken for this workshop was to assemble a group of technologists, economists, industry, regulatory and political actors and ask each of them to consider a small set of specific questions related to a future Internet. Thankfully, this exercise was not just another search for the next "Killer App", nor a design exercise for IP version 7. It was a valuable opportunity to pause and reflect on some of the sins of omission in today's Internet and ask why, and reflect on some of the unintended consequences of the Internet and ask if they were truly unavoidable consequences... more

Why I’m Standing for the ICANN Board and Why I’ve made My Statement Public

The number of applications this year for the seven positions within ICANN has been so low that the NomCom has gone to the trouble of printing up pamphlets, holding a public meeting at Marrakech and extending the deadline by a fortnight. At the two public Board sessions in Marrakech the grand hall that was provided was virtually empty, sparking some debate as to why. Susan Crawford ventured that it was because ICANN was failing to connect with people; Vint Cerf suggested that ICANN was so successful at doing its job that people didn't feel the need to attend. Mouhamet Diop pointed out that we were in a French-speaking Arabic country and no one was going to sit through four hours of discussion if they didn't understand a word of it... more

Mitigating Spoofed Attacks Using IPv6 Address Space

Timothy D. Morgan's recent paper titled, "IPv6 Address Cookies", seeks to apply the fundamental shift in resource availability brought about by the vastly increased Internet address space in IPv6 to develop a novel, lower cost solution to mitigating spoofed attacks. "Spoofed denial of service attacks have plagued the Internet for a number of years, and show no signs of abating. Research into mitigation techniques has apparently not led to a financially viable solution, and new attacks have been discovered in the wild without being widely anticipated". The following provides an introduction to this paper. more
