The Early History of Usenet, Part III: File Format

When we set out to design the over-the-wire file format, we were certain of one thing: we wouldn't get it perfectly right. That led to our first decision: the very first character of the transmitted file would be the letter "A" for the version. Why not a number on the first line, including perhaps a decimal point? If we ever considered that, I have no recollection of it. more

The Early History of Usenet, Part II: Hardware and Economics

There was a planning meeting for what became Usenet at Duke CS. We knew three things, and three things only: we wanted something that could be used locally for administrative messages, we wanted a networked system, and we would use uucp for intersite communication. This last decision was more or less by default: there were no other possibilities available to us or to most other sites that ran standard Unix. Furthermore, all you needed to run uucp was a single dial-up modem port. more

An Economic Perspective on Internet Centrality

The IETF met in November 2022 in London. Among the many sessions that were held in that meeting was a session of the Decentralised Internet Infrastructure Research Group, (DINRG). The research group's ambitions are lofty: DINRG will investigate open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery. more

Internet Evolution: Moore’s Law, Addressing Architectures, and the Future of Internet Scale

The Internet has evolved from a scarcity-driven system into one defined by abundance, reshaping infrastructure, governance, and economic models while challenging long-held assumptions about addressing, network roles, and the future of protocol design. more

Internet Society Seeks Nominations for 2026 Board of Trustees

The Internet Society is seeking nominations for its 2026 Board of Trustees. Four seats are open across its global stakeholder communities, offering an opportunity to help steer the future of a trusted, open Internet. more

Trust and Insecurity

When I was first advocating home networking at Microsoft, we encountered a problem. The existing systems and applications had implicitly assumed they were inside a safe environment and didn't consider threats from bad actors. Early Windows systems hadn't yet provided file system with access control and other protections though there were some attempts to have separate logins to keep some settings separate. more

Entering the Growing IPv4 Market: What Enterprises Should Do Now

With IPv4 addresses fetching up to $30 apiece and IPv6 adoption lagging, companies may be sitting on hidden digital assets. A strategic audit could unlock unexpected revenue and enhance long-term infrastructure planning. 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
