China’s Authorities Push to Accelerate IPv6 Adoption: Should Other Countries Take Note?

In a bid to stay ahead in the fierce global tech race, China has set a goal of running a single-stack IPv6 network by 2030. To achieve this goal of having a single IPv6 networking stack for the nation, authorities have issued time-specific milestones to relevant agencies and operators within the Chinese jurisdiction. Most notably, by the end of 2023, no new networks will be allowed to use the IPv4 – signaling immediate dramatic changes across the board. more

Potential Impacts of Large-Scale Metaverses on Internet Governance: Bandwidth

Neal Stephenson’s foundational cyberpunk novel Snow Crash brought to the public the concept of a metaverse, a virtual reality in which people interact using avatars in a manufactured ecosystem, eschewing the limitations of human existence. More recently, Ready Player One capitalized on that idea and brought it back to prominence with a bestselling novel and subsequent film adaptation. Amid rebranding efforts and seeking a new way forward, Mark Zuckerberg has made it Facebook’s (now Meta Platforms) priority to build a platform that could enable the metaverse to become a mainstream technology with the sort of reach that their social networks and WhatsApp have. more

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. more

Interplanetary Internet

We had a very interesting presentation and discussion regarding the topic of interplanetary internet with my international colleagues, of which Vint Cerf – one of the “fathers of the internet” – is also a member. As a partner of the Interplanetary Networking Special Interest Group (IPNSIG), he took us on a journey that he has been involved with over the last 20 years regarding communication networks in space. A true mind-broadening experience. more

Numerous Lessons We Can Learn From the Facebook Outage and Its Mistakes

It was only a few weeks back, in July of this year, where I remarked that an Akamai report of an outage was unusual for this industry. It was unusual in that it was informative in detailing their understanding of the root cause of the problem, describing the response that they performed to rectify the immediate problem, the measures being undertaken to prevent a recurrence of this issue, and the longer-term measures to improve the monitoring and alerting processes used within their platform. more

Transparency Meets Sustainability: Announcing the SDIA Open Data Hub

Last month, the Sustainable Digital Infrastructure Alliance (SDIA) announced our Open Data Hub, a resource that's meant to boost transparency, trust, and data availability to help researchers, industry, and society realize a sustainable digital economy. It is essentially our answer to the challenge recognized across the sector: that the lack of reliable data is one of the most foundational issues we face in creating a sustainable ICT ecosystem. more

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. more

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings. more

“It’s Always DNS!” Why DNS Is the Biggest Single Point of Failure in the New Norm

Many in the network security field may be familiar with the phrase: "It's always DNS."  This is a popular meme within the industry, often making reference to the internal domain name system (DNS), the dynamic host configuration protocol (DHCP) part of a company's online network, that whenever there is a network issue, it's always an issue with DNS. more

Transport vs. Network

One of the basic tools in network design is the so-called "stacked" protocol model. This model was developed in the late 1970s as part of a broader effort to develop general standards and methods of networking. In 1983, the efforts of the CCITT and ISO were merged to form The Basic Reference Model for Open Systems Interconnection, usually referred to as the Open Systems Interconnection Reference Model or the "OSI model." more

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. more

ECFiber: Building a Fiber-to-Premises Network in the Rural United States

Nestled in the northeastern part of the United States is the small state of Vermont, the 14th State to join the United States in 1789. Its name comes from the French, in which 'vert montagne' means 'green mountain.' and it is known as the Green Mountain state. With only about 625,000 inhabitants, it is the 45th state out of 50 in size, and 49th of 50 in number of people, even less populated than Alaska. more

A Look Back at the World of IP Addressing in 2020: What Changed and What It Means

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 around 1992, the IETF gazed into their crystal ball and tried to understand how the Internet was going to evolve and what demands would be placed on the addressing system as part of the "IP Next Generation" study.  more

An Innovative Framework That Will Help the IoT Industry Scale Into the Billions

The Internet of Things (IoT) is on an explosive growth trajectory. According to Transforma Insights, the number of IoT-connected devices is projected to increase to 24.1 billion worldwide by 2030. That's almost a three-fold increase from 2019. Much of this growth will be fueled by the coming 5G revolution, which will enable businesses and consumers to take advantage of a wide range of increasingly sophisticated connected devices. more

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
