The Christmas Goat and IPv6 (Year 13)

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

Is Secured Routing a Market Failure?

The Internet represents a threshold moment for the communications realm in many ways. It altered the immediate end client of the network service from humans to computers. It changed the communications model from synchronized end-to-end service to asynchronous and from virtual circuits to packet switching. At the same time, there were a set of sweeping changes in the public communications framework... more

Some Random Notes from IETF 115

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

Businesses Are Ready for the Metaverse

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

Looking at Centrality in the DNS

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

In Memoriam: Frederick P. Brooks, Jr. – a Personal Recollection

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

The Fibre Optic Path

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

Going Dark: How the Increasingly Dark Network Is Creating Some Pretty Ugly Choices for Site Security Administrators

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

The Short History of the Internet: From ARPANET to the Metaverse

Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

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
