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
A curious price inversion has occurred in IPv4 markets. The long-term trend that discounted large blocks has reversed. The graph identifies /15 and /16 (large) block pricing per IP address throughout the period in the form of dark spots. It is evident that, for most of the timeframe here (2014 to the first half of 2021), large blocks sold at a significant discount. One might guess that the administrative chores related to large-network needs were most efficiently and cheaply satisfied with large blocks. more
This latest initiative announced by the Coalition for Digital Africa will focus on strengthening the Internet infrastructure across the continent by enhancing five existing Internet exchange points (IXPs). The initiative is supported by a grant from ICANN and will be implemented by the Internet Society (ISOC) and will involve identifying five IXPs based on their potential to make a high impact on the respective local and sub-regional markets. more
Vinton Cerf, widely known as the "Father of the Internet," has been awarded the IEEE Medal of Honor in 2023 for his contributions to the development of the Internet architecture and for his leadership in its growth as a critical infrastructure for society. more
2022 was not a normal year for me. We sold our company of almost 25 years to Interlan Gefle AB to Nordlo Group, and I also moved away from Gävle city to Boänge, a small rural village outside Sandviken where my ISP (AS20626) still isn't ready for IPv6 in my location.... ☹ ( I use a Mikrotik with a Wireguard tunnel to solve my IPv6 today.) It's 2023 when I'm writing this, and I can't understand why ISPs still haven't deployed IPv6! more
The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF meeting. more
The latest technology on the horizon is the metaverse, which, stated simply, is the creation of online environments. While the primary focus of the metaverse is to create alternate realities, an application with a possible immediate big uptake is vertical presence for business meetings. Ciena, a manufacturer of fiber optic transmission equipment, recently did a survey worldwide of 15,000 business people to understand the interests and expectations of the metaverse. more
The Internet's Domain Name System undertakes a vitally important role in today's Internet. Originally conceived as a human-friendly way of specifying the location of the other end of an Internet transaction, it became the name of a service point during the transition to a client/server architecture. A domain name was still associated with an IP address, but that 1:1 association was weakened when we started adjusting to IPv4 address exhaustion. more
Brooks is famous for many things. Many people know him best as the author of The Mythical Man-Month, his musings on software engineering and why it's so very hard. Some of his prescriptions seem quaint today -- no one these days would print out documentation on microfiche every night to distribute to developers -- but his observations about the problems of development remain spot-on. But he did so much more. more
In August 1858, Queen Victoria sent the first transatlantic telegram to U.S. President James Buchanan. The cable system had taken a total of four years to build and used seven copper wires, wrapped in a sheath of gutta-percha, then covered with a tarred hemp wrap and then sheathed in an 18-strand wrap, each strand made of 7 iron wires. It weighed 550kg per km, with a total weight of over 1.3Mkg. more
I'd like to reflect on a presentation by Dr. Paul Vixie at the October 2022 meeting of the North American Network Operators Group (NANOG) on the topic of the shift to pervasive encryption of application transactions on the Internet today. There is a view out there that any useful public communications medium needs to safeguard the privacy and integrity of the communications that it carries. more
OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more
One of the discussion topics at the recent ICANN 75 meeting was an old favorite of mine, namely the topic of Internet Fragmentation. Here, I'd like to explore this topic in a little more detail and look behind the knee-jerk response of declaiming fragmentation as bad under any and all circumstances. Perhaps there are more subtleties in this topic than simple judgments of good or bad. more
The last few years have shown us how the Internet shrinks distances between distributed teams, organizations and families. This poses a challenge for some organizations. Many business relationships and contractual agreements involving the Internet have geographical implications and restrictions. This matters to anyone operating a network. It is most important for networks that get new address space. more
Let's take a second to look back some 50 years to the world of 1972 and the technology and telecommunications environment at that time. The world of 1972 was one populated by a relatively small collection of massive (and eye-wateringly expensive) mainframe computers that were tended by a set of computer operators working around the clock and directed by specialized programmers, trained in the obscure symbol set used by the job control systems on these computers. more
