With the upcoming celebration of the 50 years of the Internet, I'm trying to figure out how the traditional story misses the powerful idea that has made the Internet what it is -- the ability to focus on solutions without having to think about the network or providers. It's not the web -- thought that is one way to use the opportunity. The danger in a web-centric view is that it leads one to make the Internet better for the web while closing the frontier of innovation. more
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
Do you know of someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or maybe someone who has been actively working for open standards and open processes for the Internet? more
Running a DNS server that serves the root gives an interesting view into the world of the DNS. With the ongoing improvements to the ICANN operated L-ROOT, we've been fortunate enough to be able to make use of the "DNS Statistics Collector" (DSC) tool. "DSC" allows us to generate different views of the DNS queries we have been seeing at the L-ROOT systems. more
Would you like to understand the major highlights of the 96th meeting of the Internet Engineering Task Force (IETF) last month in Berlin? What were some of the main topics and accomplishments? How many people were there? What else went on? If so, you can watch a short video interview I did below with IETF Chair Jari Arkko. more
The last few weeks have reinforced the importance of modern communication networks to societies. Health care providers, schools, governments, and businesses all rely on networks that enable us to connect and collaborate remotely. Had we encountered a similar pandemic ten years ago, we would not have been able to continue our activities on the level that is possible today. more
On Thursday, Stephen J. Lukasik passed away peacefully at the age of 88. He was the legend in a field with no peer. For nearly half a century, he shaped the development of national security and network technology developments at a level and extent that is unlikely ever to be matched. For a great many of us in that arena from the 1960s past the Millennium, he was the demanding visionary leader who set the policies and directions, framed the challenges, approved and funded the projects, and questioned the results. more
The Great Renaming was a significant event in Usenet history since it involved issues of technology, money, and governance. From a personal perspective -- and remember that this series of blog posts is purely my recollections – it also marked the end of my "official" involvement in "running" Usenet. I put "running" in quotation marks in the previous sentence because of the difficulty of actually controlling a non-hierarchical, distributed system with no built-in, authenticated control mechanisms. more
I'm never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the IETF. Is this an example of a severe overload of obsessive-compulsive behaviour? Or does this single bit represent a major point of design principle... more
CIDR (Classless Inter-Domain Routing) is a routing system in which network engineers can distribute IP addresses based on the size of their specific network. This is more efficient than the previous system, which assigned IP addresses depending on whether the size of a network fits into one of only three sizes: Class A, Class B, and Class C. more
On May 19, 2024, the Internet's 50th anniversary was celebrated in a virtual event named i50, drawing participation from 1,000 IEEE members and internet enthusiasts from 56 countries. The live-streamed event was a highlight in a series of celebrations marking this milestone. more
Interested in learning more about routing security? How it can affect your connectivity supply chain? What are best practices for enterprises and organizations? What is the role of CSIRTs in securing routing? What are governments doing now, and planning to do in the future around routing security? more
In 2003, the world of network engineering was far different than it is today. For instance, EIGRP was still being implemented on the basis of its ability to support multi-protocol routing. SONET, and other optical technologies were just starting to come into their own, and all-optical switching was just beginning to be considered for large-scale deployment. What Hartley says of history holds true when looking back at what seems to be a former age: "The past is a foreign country; they do things differently there." more
Tonight (27 Sep 2019) you can watch the 2019 Internet Hall of Fame induction ceremony streaming live out of Costa Rica. Eleven individuals from six countries will be inducted into the Internet Hall of Fame (IHOF) today. The 2019 class of inductees have expanded the Internet's reach into new regions and communities, helped foster a greater understanding of the way the Internet works, and enhanced security to increase user trust in the network. more
Project Liberty's Institute sat down with Dave Clark, an early contributor to the TCP/IP protocols that built and run the Internet, and one of the expert advisors on DSNP, the Decentralized Social Networking Protocol. Dave Clark is Senior Research Scientist at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Fellow of the National Academy of Engineering and the American Academy of Arts and Sciences. more
