IPv6 Transition

How Much Longer Is This IPv6 Transition Going to Take?

The saga of the IPv6 transition continues to surprise us all. RFC 2460, the first complete effort at a specification of the IPv6 protocol, was published in December 1998, more than twenty years ago. The entire point of IPv6 was to specify a successor protocol to IPv4 due to the prospect of running out of IPv4 addresses. Yet we ran out of IPv4 addresses more than a decade ago.

Another Year of the Transition to IPv6

I bet that nobody believed in 1992 that thirty years later, we'd still be discussing the state of the transition to IPv6! In 1992 we were discussing what to do about the forthcoming address crunch in IPv4, and having come to terms with the inevitable prospect that the silicon industry was going to outpace the capacity of the IPv4 address pool in a couple of years, we needed to do something quickly

The Changing Role of IP Addresses in the Architectural Evolution of the Internet

I work at APNIC, the Regional Internet Registry that serves the Asia Pacific Region. APNIC provides common infrastructure services for the region that support the unique assignment of IP address blocks to Internet network operators within our region through the operation of an address registry. In short, IP addresses are what we do. So, when there are discussions in technology circles about evolving the Internet's address model in varying ways,...

The Christmas Goat and IPv6 (Year 12)

This year could be the fifth year in a row where the goat isn't burned down. But early in the morning of Dec 17th, it was on fire by an arsonist who got caught a few minutes later. So Stephan Lagerholm, who had visited me earlier for some IPv6 site seeing in Gävle and I were lucky to get this photo. The traffic went down by 5% from last year, and I don't have any good explanation for that. The visitors with many hits in the logs are always from the same countries where North America and Europe are dominating.

The Formation of IPv4 Address Markets

Something odd happened through 2021 in the market for IPv4 addresses. Across 2021 the reported market price for the transfer of IPv4 addresses has doubled, from approximately USD $27 per IPv4 individual address at the end of 2020 to around USD $55 per address in December 2021. It has taken seven years for the market price to rise from just under USD $10 to get to USD $20 per address. The next year, 2020, saw the price rise a further USD $7 per address, and then in the next 12 months, the market price doubled.

Notes from NANOG 83

The network operations community is cautiously heading back into a mode of in-person meetings, and the NANOG meeting at the start of November was a hybrid affair with a mix of in-person and virtual participation, both by the presenters and the attendees. I was one of the virtual mob, and these are my notes from the presentations I found to be of personal interest. I hope you might also find them to be of interest as well... The year 2021 has not been a good year for Internet outages.

Fifty Years On – What to Expect in the Next 50 Years of the Internet

When did the Internet begin? It all gets a bit hazy after so many years, but by the early 1970s, research work in packet-switched networks was well underway, and while it wasn't running TCP at the time (the flag day when the ARPANET switched over to use TCP was not until 1 January 1983) but there was the base datagram internet protocol running in the early research ARPA network in the US. Given that this is now around 50 years ago, and given that so much has happened in the last 50 years, what does the next 50 years have in store?

The Irrationality of Deploying IPv6

For the past few decades, there's been a relatively straightforward narrative on the economics behind the IPv6 transition that goes something like this: sooner or later, IPv4 scarcity will drive costs up until they exceed those of deploying IPv6. A competitive market will then make the rational choice and transition to a more efficient mode of production and deploy IPv6. This is textbook economics, and - with the disclaimer that I'm not a trained economist - it appears to be incorrect.

Still Waiting for IPv6

It's now been a decade since the world officially ran out of blocks of IP addresses. In early 2011 the Internet Assigned Numbers Authority (IANA) announced that it had allocated the last block of IPv4 addresses and warned ISPs to start using the new IPv6 addresses. But here we are a decade later and not one of my clients has converted to IPv6.

An IPv6 Update for 2020

The Australian Domain Name Administration, AUDA, recently published its quarterly report for the last quarter of 2020. The report contained the interesting snippet: "The rapid digitization of our lives and economy -- necessitated by COVID-19 -- continued to underpin strong growth in .au registrations. New .au domains created in December 2020 were up 23 percent from December 2019, while total domains under management were up more than 2.1 percent over the same period."
