RIPE held a community meeting in May in Rotterdam. There were a number of presentations that sparked my interest, but rather than write my impressions in a single lengthy note, I thought I would just take a couple of topics and use a shorter, and hopefully more readable bite-sized format.…
It has been almost a decade since Edward Snowden exposed a program of mass surveillance by the US NSA, using the Internet for large scale data harvesting. The Internet had been profligate in the way in which various protocol scattered user data around with a somewhat cavalier disregard for privacy.…
The early days of the Internet were marked by a constant churn of technology. For example, routing protocols came and went in rapid succession, transmission technologies were in a state of constant flux, the devices we used to interact with the emerging digital environment were changing, and the applications we…
Author: Geoff Huston 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…
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…
Two years ago, I wrote an article on X.509 certificate revocation. I’d like to report that a lot has happened between then and now, but that’s not the case. So why revisit this topic today? What drew my attention was a tweet earlier this month that reported that the Certification…

All the material presented at the meeting can be found at https://ripe83.ripe.net/. Vulnerability Disclosure Responsible Disclosure is a…
The network operations community is cautiously heading back into a mode of in person meetings and the NANOG meeting at the start of November was a hybrid affair with a mix of in-person and virtual participation, both by the presenters and the attendees. I was one of the virtual mob,…
It has often been said of technology standards that the good thing is that there are just so many to pick from! The same is true, to perhaps a more limited extent, in the world of cryptography. The choices may not be quite so diverse, but there are still many…
Am I really talking to you? In a networked world that’s an important question. For example, where I’m located, when I look up the DNS name www.google.com I get the IPv6 address 2404:6800:4006:813::2004. This implies that when I send an IPv6 packet to this destination address I will reach a…
