Examining IPv6 Performance - Revisited

Every so often I hear the claim that some service or other has deliberately chosen not to support IPv6, and the reason cited is not because of some technical issue, or some cost or business issue, but simply because the service operator is of the view that IPv6 offers an inferior level service as compared to IPv4, and by offering the service over IPv6 they would be exposing their clients to an inferior level of performance of the service. more»

Developing Internet of Things Building Blocks


The Internet is undergoing an evolutionary transformation resulting from the explosive growth of things that are interconnected. From single purpose sensors through wearable technologies to sophisticated computing devices, we are creating, exchanging, and consuming more data at rates that would have been inconceivable just a decade ago. The market suggests the average consumer believes this is the best world possible. As technologists, we have a responsibility to consider if we are building an Internet that is in the best interest of the user. more»

Is There a Positive Business Case for IPv6? We Are About to Find Out, If You Help Us…

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»

Google's IPv6 Stats Hit 12% on Fourth Anniversary of World IPv6 Launch

Four years ago today, thousands of websites, including Facebook, Google and Yahoo, and hundreds of networks permanently enabled IPv6 in what was called "World IPv6 Launch". One year before, on June 6, 2011, there had been a 24-hour test in "World IPv6 Day" but by June 6, 2012, IPv6 was enabled permanently for the participating sites and networks. One of the many IPv6 statistics sites many of us have watched since that time has been Google's statistics. more»

Is IPv6 an Essential Precondition for Internet of Things? Or Are Things Just Fine with IPv4?

It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they are mutually reliant. An Internet of Things needs the massively expanded protocol address space that only IPv6 can provide, while IPv6 needs to identify a compelling use case to provide a substantive foundation to justify the additional expenditures associated with a widespread deployment of this new protocol that only the Internet of Things can provide. more»

On the Internet Everyone is Connected to Everyone Else - Right?

We tend to make a number of assumptions about the Internet, and sometimes these assumptions don't always stand up to critical analysis. We were perhaps 'trained' by the claims of the telephone service to believe that these communications networks supported a model of universal connectivity. Any telephone handset could establish a call with any other telephone handset was the underlying model of a ubiquitous telephone service, and we've carried that assumption into our perception of the Internet. On the Internet anyone can communicate with anyone else - right? more»

Behind the Curtain: Making IPv6 Work

Wouldn't it be nice if turning on IPv6 really was 'press one button and the rest is magic' easy? For some things, it is. If you're talking about client-side, enabling an IPv4-only home service on DSL or fibre really can be this simple, because all the heavy lifting is being done inside your ISP: you're not enabling IPv6 in the network, you're turning on the last mile. It was knocking at your door and you just had to let it in. more»

IPv6 and DNSSEC Are Respectively 20 and 19 Years Old. Same Fight and Challenges?

A few weeks ago I came across an old interview of me by ITespresso.fr from 10 years back entitled "IPv6 frees human imagination". At the time, I was talking about the contributions IPv6 was expected to make and the challenges it had to face. After reading the article again, I realized that it has become a little dusty (plus a blurred photo of the interviewee :-)). But what caught my attention the most in the interview was my assertion: "If IPv6 does not prevail in 2006, it's a safe bet that it will happen in 2007". Wow! more»

Addressing 2015 - Last One Standing!

Time for another annual roundup from the world of IP addresses. What happened in 2015 and what is likely to happen in 2016? This is an update to the reports prepared at the same time in previous years, so let's see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. more»

Global IPv6 Deployment Now Passes 10%!

Global IPv6 deployment just passed a major milestone over the past few days when Google's IPv6 adoption statistics showed over 10% of users connecting to Google's sites coming in over IPv6. Considering that only two years ago I wrote here on CircleID about IPv6 passing the 3% adoption mark, this is a great amount of growth to see! If you look on the "per-country" tab of Google's stats you will see that in some countries deployment is much higher. For example, around 25% in the USA, Portugal and Germany, 31% in Switzerland and 44% in Belgium. more»

The Christmas Goat and IPv6 (Year 6)

When I last year failed to take a picture of the Christmas goat before it was taken down, I decided this year to take a pic every minute, just to be on the safe side. A shortened movie based on these pics of the 2015 Christmas Goat can be find on YouTube. The clip on YouTube also shows that in the early morning of December the 27th the goat was set on fire and burned down in minutes. more»

New Trend: Vanity IPv6 Addresses

It's like a vanity license plate, but for your IP address. Previously under IPv4 DNS registration, users were limited to only using numbers. However, with the height of IPv6 underway users are getting creative with their newfound use of characters. Although you can only use characters A-F, it only takes a little creativity to find ways around this. more»

Apple and IPv6 - Not Quite There Yet

It's Apple's Developers Conference time again, and in amongst the various announcements was week, in the "Platforms Status of the Union" presentation was the mention of Apples support of IPv6. Sebastien Marineau, Apple's VP of Core OS told the conference that as far as IPv4 addresses are concerned, exhaustion "is finally here", noting that this already started in 2011 in the Asia Pacific while in North America IPv4 address exhaustion is imminent. Sebastien noted that it's really important to support IPv6 in devices and applications these days... more»

The Internet of Stupid Things

In those circles where Internet prognostications abound and policy makers flock to hear grand visions of the future, we often hear about the boundless future represented by "The Internet of Things". This phrase encompasses some decades of the computing industry's transition from computers as esoteric piece of engineering affordable only by nations, to mainframes, desktops, laptops, handhelds, and now wrist computers. Where next? more»

IPv6 Security Myth #5: Privacy Addresses Fix Everything!

Internet Protocol addresses fill two unique roles. They are both identifiers and locators. They both tell us which interface is which (identity) and tell us how to find that interface (location), through routing. In the last myth, about network scanning, we focused mainly on threats to IPv6 addresses as locators. That is, how to locate IPv6 nodes for exploitation. Today's myth also deals with IPv6 addresses as identifiers. more»
