The Dual-Front Challenge: Why Route Security (RPKI) is the Prerequisite for Quantum Readiness (PQC)

Internet security risks advancing unevenly: post-quantum cryptography may protect data while vulnerable routing still enables hijacks. Universal RPKI adoption, paired with cryptographic agility, is essential to build an Internet trust architecture ready for quantum threats. more

The Web Has Become a Content Delivery Network

Cyberattacks, AI scraping and relentless bot traffic have transformed CDNs from performance tools into the Web's defensive gatekeepers, reshaping Internet architecture, governance and control as private intermediaries increasingly determine which requests reach origin servers first. more

The Logic, Fallacy and Flaws Associated With IPv4 Network Resource Transfers

Fifteen years after IPv4 exhaustion, a transfer market has reallocated scarce address space, enabling internet growth, despite uneven registry policies, opaque fees, and lingering resistance to a system that proved more pragmatic than planned reclamation. more

When Registry Power Detaches From Liability, It Detaches From Reality

IPv4 scarcity turned regional internet registries from clerks into gatekeepers of a valuable resource. Yet liability caps remain trivial, leaving powerful institutions with little accountability and incentives for conflict and structural breakdown ahead. more

From Guessing to Declaring: Why Geofeed is the Sovereign Foundation of Global Network Resilience

As IP addresses move across borders, outdated geolocation guesses cause service failures and regulatory risks. Geofeed and Signed Geofeed replace inference with verified declarations, promising accurate, resilient and sovereign foundations for global internet infrastructure governance. more

David J. Farber, Early Architect of the Internet, Dies at 91

David J. Farber, a pioneering computer scientist and mentor to key architects of the Internet Protocol, has died at 91, leaving a legacy that helped transform isolated machines into the global network underpinning modern communication. more

Seven Stages of the Internet

The Internet is evolving far beyond screens and smartphones. A proposed seven-stage framework anticipates a future shaped by autonomous agents, sensory wearables, global connectivity, and quantum networks redefining how humans interact with the digital world. more

The Governance of the Root of the DNS

The arrangements regarding the composition and organisation of the provision and operation of authoritative root servers are one of the more long-lasting aspects of the public Internet. In the late 1980s, Jon Postel, as the IANA, worked with a small set of interested organisations to provide this service. It was informally arranged, without contracts and without payment of any form. more

Ossification and the Internet

Networks are typically built to provide certain services at an expected scale. The rationale for this focused objective is entirely reasonable: to overachieve would be inefficient and costly. So, we build service infrastructure to a level of sufficient capability to meet expectations and no more. In ideal conditions, this leads to a widely deployed and highly efficient infrastructure that is capable of supporting a single service profile. more

Remembering Dave Taht

Dave Taht died on April 1st. I met him only recently, and never in person, but his passing saddens me. His technical work and evangelism have improved the Internet, and I will give some examples of his contributions to the Internet community and users, but I am sad because he was a good person -- idealistic, unselfish, open, and funny. I'll miss him. First, his contributions, then his values. more

IPv6 Transition Stalls as Internet Moves Beyond IP Addresses

The shift from IPv4 to IPv6 has been a protracted and complex process, raising questions about why this transition has been so sluggish despite the depletion of IPv4 addresses more than a decade ago. more

Digital Sovereignty and Internet Standards

There have been a number of occasions when the Internet Engineering Task Force (IETF) has made a principled decision upholding users' expectations of privacy in their use of IETF-standardised technologies. (Either that, or they were applying their own somewhat liberal collective bias to the technologies they were working on!) The first major such incident that I can recall is the IETF's response to the US CALEA measures. more

Monumental Cybersecurity Blunders

Two recent celebrated cybersecurity standards history events brought together sets of people who were intimately involved with some of the most significant network security standards work ever undertaken. These included the X.509 digital certificate standards at ITU X.509 Day, and the Secure Digital Network System (SDNS) standards at the NSA Cryptologic History Symposium 2022. more

Communities of Things

When I want to go to a website, I just type in the URL, and I'm there. Sure, we had to get a subscription from a service provider and set up our devices, but that was a one-time thing. As we move into a world of many connected devices, it's no longer a one-time thing. Today, creating connected devices and services requires thinking about all the mechanics and networking and onboarding and providers. more

The IETF Evolution

The Internet Engineering Task Force (IETF) is a collaborative body that has developed internetworking specifications for more than five decades, successfully shaping the global marketplace of digital network equipment and services. Beginning as a kind of distributed think tank among network researchers in 1969, it evolved to become one of the world's most influential standards bodies. more
