The Christmas Goat and IPv6 (Year 10)

This year marked the 10th anniversary of collecting statistics for IPv6 from the Christmas Goat. It's the third year now with almost no snow, and with this crazy winters and climate, it's hard to get any good photos of the goat. The photo is only from 3–4 days in early December with little snow so far in Gävle.The measurements this year started very low with 20% IPv6, but it made some improvements and landed just like 2018 at a total of 41%. more

The 2019 IPv4 Market: Mid-Year Report

After a slow start to 2019, the volume of IPv4 numbers traded is picking up – though still far below the peak trading periods of 2018. By this same time last year, the total quantity of numbers flowing to and from organizations in the ARIN region was just over 27 million. more

Network Protocols and Their Use

In June, I participated in a workshop, organized by the Internet Architecture Board, on the topic of protocol design and effect, looking at the differences between initial design expectations and deployment realities. These are my impressions of the discussions that took place at this workshop. ... In this first part of my report, I'll report on the case studies of two protocol efforts and their expectations and deployment experience. more

Digging Into IPv6 Traffic to Google: Is 28% Deployment Really the Limit?

After some years of accelerating IPv6 deployment, we are now into a period of slower growth and it's not clear where we are heading. It is therefore interesting to try to predict the future of IPv6 over the coming years. At Ericsson Research, we have been working on this topic since 2013, but just recently created a forecast model that seems to be quite accurate. However, it gives a disappointing message of a very low final level of IPv6 deployment at less than 30%! more

A Look Back at the World of IP Addressing in 2018: What Changed and What to Expect

Time for another annual roundup from the world of IP addresses. 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. Back in around 1992 the IETF gazed into the crystal ball and tried to understand how the internet was going to evolve and what demands that would place on the addressing system as part of the "IP Next Generation" study. more

It is once again time for our annual review of posts that received the most attention on CircleID during the past year. Congratulations to all the 2018 participants for sharing their thoughts and making a difference in the industry. more

Who Played a Major Role in Advancing the Internet? Nominations Open for 2019 Internet Hall of Fame

Do you know someone who has played a major role in the development and advancement of the Internet? Now is the time to recognize their contribution. Nominate them for the 2019 Internet Hall of Fame. With more than 100 inductees, the Internet Hall of Fame celebrates Internet pioneers and innovators who have pushed the boundaries to bring the Internet to life and make it an essential resource for billions of people today. more

The Christmas Goat and IPv6 (Year 9)

Here we are with the ninth year of measuring IPv6 on the Christmas Goat. Last year we had almost no snow and it's almost the same this year. This year I give you 50 seconds of "action" film with the goat from the early in December. But the measurement was a big disappointment. They started high with 60% IPv6 and went down to 41% at the end. But as can be seen with the progress, next year we should easily break the 50% barrier! more

IPv6 in China

Much has been written about the progress of the adoption of IPv6 over the years. I know I've been guilty of adding my writings into the pool, and this article is a further contribution to that pool of observations and measurements. In this case, I want to look in some detail at the deployment of IPv6 in China. Why is China so important in this story of IPv6 deployment? more

IPv6 Security Considerations

When rolling out a new protocol such as IPv6, it is useful to consider the changes to security posture, particularly the network's attack surface. While protocol security discussions are widely available, there is often not "one place" where you can go to get information about potential attacks, references to research about those attacks, potential counters, and operational challenges. more
