Large-scale IPv6 deployments suggest that IPv6 is at least a technical success, the technology works. Time to visit the other important question: does it work commercially. Does IPv6 really come with a positive business case? We are about to find out, if you help us... The Internet technical community has spent about two decades making IPv6 work on a technical level. We have developed the protocol, modified and expanded a few others; we set up the registry system and distributed the addresses. more
A decade has passed since Jon Postel left our midst. It seems timely to look back beyond that decade and to look forward beyond a decade hence. It seems ironic that a man who took special joy in natural surroundings, who hiked the Muir Trail and spent precious time in the high Sierras was also deeply involved in that most artificial of enterprises, the Internet. more
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
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
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
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
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
Here we are with CircleID's annual roundup of top ten most popular posts featured during 2014 (based on overall readership). Congratulations to all the participants whose posts reached top readership and best wishes for 2015. more
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
The new year is upon us and it's time for our annual look at CircleID's most popular posts of the past year and highlighting those that received the most attention. Congratulations to all the 2016 participants and best wishes to all in the new year. more
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
Network operators rely on guidance from IP address experts because not all IP addresses used on the Internet are the same. The "reputation" of email senders is especially important because some are malicious users of the system. But identifying "senders" based on their email addresses or the individual IP address of a user presents issues that are unnecessarily complex. more
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
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
Interesting things happening in China. An article in the English edition of the People's Daily on line is headlined, Decimal network security address begins operation: "China's decimal network security address was officially launched. China has made a fundamental breakthrough in its Internet development; and actual use has been successful. The birth of decimal network technology makes China the only country able to unify domain names, IP addresses and MAC addresses into the text of a metric system..." Someone asked whether this was a rumored IPv9? It appears IPv9 is a project name, not a new protocol. It lumps together several activities, including at least... more
