Scaling the Root of the DNS

The DNS is a remarkably simple system. You send it queries, and you get back answers. Within the system, you see exactly the same simplicity: The DNS resolver that receives your query may not know the answer, so it, in turn, will send queries deeper into the system and collects the answers. The query and response process is the same, applied recursively. Simple. However, the DNS is simple in the same way that Chess or Go are simple... more

Maximizing Qname Minimization: A New Chapter in DNS Protocol Evolution

Data privacy and security experts tell us that applying the "need to know" principle enhances privacy and security, because it reduces the amount of information potentially disclosed to a service provider -- or to other parties -- to the minimum the service provider requires to perform a service. This principle is at the heart of qname minimization, a technique described in RFC 7816 that has now achieved significant adoption in the DNS. more

TLD Maintenance Significantly Improved With the New Registry Maintenance Notifications for EPP

Three years ago, the first Internet-Draft on Registry Maintenance Notifications for the Extensible Provisioning Protocol (EPP) was published, which will become a Request for Comments (RFC). The IETF Registration Protocols Extensions (REGEXT) working group is the home of the coordination effort for standards track EPP extensions. They released eight RFCs over the last couple of years, and they are currently working on more than 15 Internet-Drafts. more

Beyond the Interweb

Today's Internet is a network of networks and seen through the lens of the web. We need to look beyond the engineering history to see the Internet in the context of the broader vision of JCR Licklider, an acoustic psychologist, and his vision of man/computer symbiosis... JCR Licklider would've been thrilled to see such a powerful man-machine symbiosis becoming so normal and having it work so well. Lick, as he was called, can be considered the grandfather of the Internet. more

2020's New Internet Success – Rejoinder

The posting with a similar name seems a bit contrived by anonymous in some strange attempt to enhance its significance. Many others, including myself, have been discussing this subject for some time. Indeed, a concerted lobbying effort and anti-competitive efforts by legacy TCP/IP internet stakeholders have been really ramped up over the past year to mischaracterize what is occurring. more

2020's New Internet Success

Chinese technology policy is now more effective even than their naval posture in the South China Sea, and both are playing out in full sunshine. This success is not about the hardware pillar of Chinese tech policy, though: its focus is the structural approach China and, increasingly, other stakeholders are taking to global Internet Governance... Late in the Year of the Pig just gone, China's offer of a New Internet Protocol was chewed over in senior-level advisory groups of the International Telecommunication Union (ITU)... more

Evolving the Internet Through COVID-19 and Beyond

As we approach four months since the WHO declared COVID-19 to be a pandemic, and with lockdowns and other restrictions continuing in much of the world, it is worth reflecting on how the Internet has coped with the changes in its use, and on what lessons we can learn from these for the future of the network. The people and companies that build and operate the Internet are always planning for more growth in Internet traffic. more

Marking the 30th Anniversary of the Internet and Cybersecurity Treaty

Next week on 1 July 2020 marks the 30th anniversary of one of the most significant treaty instruments in modern times. On 1 July 1990, the Melbourne Treaty came into force as the first and only global treaty that enabled worldwide internets and mobile networks to exist, together with the cybersecurity provisions designed to protect those infrastructures. The achievement remains as an enduring tribute to Richard Edmund Butler of Australia who was one of the most influential, and best-loved Secretaries-General of the ITU. 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
