Recognizing Lessons Learned From the First DNSSEC Key Rollover, a Year Later

A year ago, under the leadership of the Internet Corporation for Assigned Names and Numbers (ICANN), the internet naming community completed the first-ever rollover of the cryptographic key that plays a critical role in securing internet traffic worldwide. The ultimate success of that endeavor was due in large part to outreach efforts by ICANN and Verisign which, when coupled with the tireless efforts of the global internet measurement community, ensured that this significant event did not disrupt internet name resolution functions for billions of end users. more

A Better PIR Deal – Maintaining Trust Is Good Business

I run a business. For years I've been in the ICANN Business Constituency, holding a series of different positions including Chair. Suffice it to say, I'm absolutely ok with making money and generally speaking, letting markets work. I also care about NGOs. For years our firm worked with PIR on the .NGO project. We got to see up close the role PIR has played as a supporter of NGOs online -- encouraging best practice, helping push out DNSSEC to a global audience, working on DNS abuse issues, supporting the sector. more

The Early History of Usenet, Part V: Authentication and Norms

We knew that Usenet needed some sort of management system, and we knew that that would require some sort of authentication, for users, sites, and perhaps posts. We didn't add any, though -- and why we didn't is an interesting story. The obvious solution was something involving public key cryptography, which we (the original developers of the protocol: Tom Truscott, the late Jim Ellis, and myself) knew about: all good geeks at the time had seen Martin Gardner's "Mathematical Games" column... more

Showing our Ethos with .ORG

I recently stepped into a new role as Chief Purpose Officer of Ethos Capital, a specialized investment firm focused on helping companies drive growth and transformation through technology. In doing so, we are committed to operating ethically, responsibly, and in the best interests of all stakeholders, including employees, customers, vendors and the broader community. more

The 5G Race in Reno

The past week in the 5G world was notable because of some major events in Reno in the 5G race to roll out the full 5G specifications known as Release 16. A set of seven major concurrent industry standards meetings were hosted there over five days last week. The metrics are indicative of who really participates in and shapes the rapidly emerging 5G platforms. more

Advancing Cyberstability: Protect the Public Internet Core and Improve Cyber Hygiene

The Paris Peace Forum (PPF), established by the French president Emanual Macron, was picked by the Global Commission for Stability in Cyberspace (GCSC) to launch its final report "Advancing Cyberstability" for good reasons: The Internet isn't just a purely technical issue with some political implications anymore. On the eve of the 2020s, the management of cyberspace is a global problem, a matter of international security, a question of war or peace. more

The Early History of Usenet, Part IV: Implementation and User Experience

To understand some of our implementation choices, it's important to remember two things. First, the computers of that era were slow. The Unix machine at UNC's CS department was slower than most timesharing machines even for 1979 – we had a small, slow disk, a slow CPU, and – most critically – not nearly enough RAM. Duke CS had a faster computer – they had an 11/70; we had an 11/45 -- but since I was doing the first implementation, I had to use what UNC had. (Log in remotely? more

Nielsen’s Law of Internet Bandwidth

One of the more interesting rules-of-thumb in the industry is Nielsen's Law of Internet bandwidth, which states that: A high-end user's connection speed grows by 50% per year. This 'law' was postulated by Jakob Nielsen of the Nielsen Norman Group in 1998 and subsequently updated in 2008 and 2019. Nielsen started by looking at usage for himself and other big data users, going back to a 300 bps (bits per second) modem used in 1984. more

Thoughts of an ICANN Public Interest Stakeholder on the Intended Sale of the .ORG Registry

The announcement of the intended Internet Society (ISOC) sale of the .ORG registry to Ethos Capital has caused a lot of frustration and anger while raising a lot of questions.
It's more than just about the money. It's more than who is behind it. It's about the soul of the DNS and the ICANN community with its multi-stakeholder model. Let's remember that the Public Interest Registry (PIR) was created, with ISOC as its sole legal owner, to provide ISOC with the funds to operate and to run the registry more-or-less as a Social Business. more

5G for Fixed Connectivity in Cuba

ETECSA reports that over 110,100 Cuban households have DSL connectivity using their Nauta Hogar service. There are also shared facilites – 986 WiFi hotspots (127 in Havana) and 347 Navigation Rooms (44 in Havana) with 1,309 computers (304 in Havana). These services are dead-ends on the road to hoped-for "computerization." The Cuban population is around 11 million so, after three years, roughly one person in 100 lives in a Nauta home and the services are limited geographically... more

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

The Early History of Usenet, Part I: The Technological Setting

Usenet -- Netnews -- was conceived almost exactly 40 years ago this month. To understand where it came from and why certain decisions were made the way they were, it's important to understand the technological constraints of the time. Metanote: this is a personal history as I remember it. None of us were taking notes at the time; it's entirely possible that errors have crept in, especially since my brain cells do not even have parity checking, let alone ECC. Please send any corrections. more

Cybersecurity Standards Practices as Cyber Threats

One of the most embarrassing and pernicious realities in the world of cybersecurity is the stark reality that some industry cybersecurity standards practices are themselves cyber threats. How so? Most industry and intergovernmental standards bodies serve as means for assembling the constantly evolving collective knowledge of participant experts and package the resulting specifications and best practices as freely available online documents to a vast, diverse universe of users. more

Do Cable Companies Have a Wireless Advantage?

The big wireless companies have been wrangling for years with the issues associated with placing small cells on poles. Even with new FCC rules in their favor, they are still getting a lot of resistance from communities. Maybe the future of urban/suburban wireless lies with the big cable companies. Cable companies have a few major cost advantages over the wireless companies, including the ability to bypass the pole issue. The first advantage is the ability to deploy mid-span cellular small cells. more
