A Look at DNS Trends and What the Future May Hold

We used to think of computer networks as being constructed using two fundamental common infrastructure components: names and addresses. Every connected device had a stable protocol address to allow all other devices to initiate a communication transaction with this device by addressing a data packet to this protocol address. And every device was also associated with a name, allowing human users and human use applications to use a more convenient alias for these protocol addresses. more

Technology Adoption in the Internet

How are new technologies adopted in the Internet? What drives adoption? What impedes adoption? These were the questions posed at a panel session at the recent EuroDiG workshop in June. In many ways, this is an uncomfortable question for the Internet, given the Internet's uncontrolled runaway success in its first two decades. The IPv4 Internet was deployed about as quickly as capital, expertise, and resources could be bought to bear on the problem... more

Emerging Communications Technologies

A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last. more

Societies Running on Quicksand: A Critical Look at Today’s Networks

The last few weeks have reinforced the importance of modern communication networks to societies. Health care providers, schools, governments, and businesses all rely on networks that enable us to connect and collaborate remotely. Had we encountered a similar pandemic ten years ago, we would not have been able to continue our activities on the level that is possible today. 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

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

How Do You Know if You’re Choosing the Best IP Geolocation API?

If you can't address your customers and the people interacting with your network face to face, at least know where they are -- anywhere in the world, anytime you want to. That's possible with geolocation technology, and many businesses are keen on acquiring the best IP geolocation API for cybersecurity and other purposes. However, before committing to a particular solution, each product needs to be carefully evaluated according to the exact needs of a prospective buyer. more

The IPv4 Market Runs on All Cylinders in 2018

2018 was a record-breaking year for the IPv4 market. The total volume of addresses traded, overall number of transactions in the ARIN region, and prices reached their highest levels to date. Since 2014, the number of transactions has grown considerably, mostly attributable to a dramatic increase in small block trades of fewer than 4,000 addresses. The volume of addresses sold during the same period, however, tells a different story. 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

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
