IPv6 Transition

Asia Pacific IPv4 Exhausted, Becomes First Region Unable to Meet IPv4 Demand

Asia Pacific Network Information Center (APNIC) today announced it has reached the last block of its available pool of IPv4 addresses. The day is marked as key turning point which initiates a major change in regional delegation policy. more

Why 2008 Was a Milestone Year for IPv6

The beginning of the year saw IPv6 added to the DNS root, closing a major hole for IPv6-only communication. In mid-year, the US federal government's IPv6 mandate came into effect, requiring all federal IP backbones to support IPv6. While the mandate didn't have anywhere near the effect that many had hoped for, it did spur many vendors to add IPv6 support to their products. The amount of observed IPv6 traffic increased considerably, but we still lack good data for how much IPv6 is being used. So, where were we at the end of 2008? more

IPv6 Transitional Uncertainties

The telecommunications industry has been around for quite some time. Whether you take it as a starting date the first efforts with the wired telegraph in the 1830's, or the telephone in the 1870's, this industry has been around for quite a long time. During this periods it has made huge achievements, and there is no doubt that the impacts of this industry have changed our lives in many ways... It is literally amazing that this industry has managed to preserve dial tone on telephone handsets while completely changing the underlying network and switching fabric of the telephone system numerous times. more

Borders, In Bankruptcy, Aims To Sell 65,536 IPv4 Addresses at $12/Address

With IPv4 address exhaustion upon us, it appears that the going market rate for IPv4 addresses is now $12/address. Over at the Register, Kevin Murphy reports on a bankruptcy filing from Borders seeking to sell a /16 block of to healthcare software vendor Cerner for a total of $786,432. At $12 per IPv4 address, this sets a new public record given that the previous high was Microsoft's acquisition of a block of Nortel IPv4 addresses... more

Microsoft Direct Access: Is it Heaven or Hell for IPv6?

I must confess, during the past couple of years I have highlighted the VPN-solution Direct Access (DA) from Microsoft as a killer application for IPv6. I still have hope for this solution, but as I now have had the chance to study the UAG/DA-solution more closely and in practical implementation, I must also highlight some issues for Microsoft to handle. My conclusion is that using DA today brings difficulties when it comes to an organization that already has, or wants to, deploy native IPv6 internally. more

IPv4 Exhaustion, 5 Implications for Africa Running out Last

I spend most of my time teaching engineers in different countries how to plan and deploy IPv6 networks. Over the last two years, I have been speaking more and more to non-engineers. These are either technology executives who sense that they need to do something about this "IPv6" thing, or government IT leaders who want to understand what the problem is and more importantly, what they could do. The most impactful part of these these exchanges is when I get these managers to understand the implications of IPv4 address exhaustion to their organisations. more

World IPv6 Day: A Year in the Life

On the 6th June 2012 we held the World IPv6 Launch Day. Unlike the IPv6 event of the previous year, World IPv6 Day, where the aim was to switch on IPv6 on as many major online services as possible, the 2012 program was somewhat different. This time the effort was intended to encourage service providers to switch on IPv6 and leave it on. What has happened since then? Have we switched it on and left it on? What has changed in the world of IPv6 over the past 12 months? Who's been doing all the work? more

An Opinion in Defence of NATs

Network Address Translation has often been described as an unfortunate aberration in the evolution of the Internet, and one that will be expunged with the completion of the transition of IPv6. I think that this view, which appears to form part of today's conventional wisdom about the Internet unnecessarily vilifies NATs. In my opinion, NATs are far from being an aberration, and instead, I see them as an informative step in the evolution of the Internet, particularly as they relate to possibilities in the evolution of name-based networking. Here's why. more

Akamai Reports 460 Times Increase in IPv6 Requests Over Its Platform Since Last Year

In its latest State of the Internet report, Akamai has highlighted industry numbers showing imminent global exhaustion of IPv4 addresses. Report has also identifies 460 times increase in IPv6 requests over Akamai's platform from June 2011 – June 2012. A fair amount of the IPv6 request growth is attributed to the "World IPv6 Launch" event held on Jun 6, 2012 organized by the Internet Society. more

CENTR Paper on Fifth World Telecommunication/ICT Policy Forum

Many nations, particularly from the developing world, look to the International Telecommunications Union (ITU) for advice on telecommunications issues and, increasingly, Internet governance issues. The ITU's Fifth World Telecommunication / ICT Policy Forum (WTPF-13), 14-16 May 2013, Geneva, Switzerland, will be the first WTPF to focus exclusively on Internet issues. more

The Ultimate Solution to Internet Governance: Let ITU and ICANN compete

Controversies over ICANN led to the creation of the Working Group on Internet Governance, but so far there have been few specific proposals for change. The Internet Governance Project has entered that breach with a new policy paper: "What to Do About ICANN: A Proposal for Structural Reform." The proposal, by Hans Klein and myself, proposes three clean, clear but probably controversial solutions to the criticisms that have been made of ICANN. more

WGIG Too Focused on Negative Side of the Internet?

The following is a report by Susan Crawford at the ICANN meeting in Cape Town where a workshop was held yesterday for increasing awareness and understanding of United Nation's World Summit on the Information Society (WSIS) and issues that directly impact ICANN. "WSIS" is defined as a process in which governments intend to address a broad range of international legal, regulatory, economic, and policy issues related to the Internet. Some governments have proposed that an intergovernmental organization be responsible for "Internet governance," a phrase that remains undefined and some consider to include and/or mean the administration and coordination of the domain name system (DNS). more

IPv6 Adoption Brings New Security Risks
