Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. Back in around 1992 the IETF…
It has become either a tradition, or a habit, each January for me to report on the experience with the inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection…
Much has been written about the progress of the adoption of IPv6 over the years. I know I’ve been guilty of adding my writings into the pool, and this article is a further contribution to that pool of observations and measurements. In this case I want to look in some…
One year ago, in late 2017, much of the policy debate in the telecommunications sector was raised to a fever pitch over the vexed on-again off-again question of Net Neutrality in the United States. It seemed as it the process of determination of national communications policy had become a spectator…

What’s this all about? Background When the Internet outgrew its academic and research roots and gained some prominence and…

Here’s what I took away from the recent 29th meeting of OARC, held in Amsterdam in mid-October 2018. Cloudflare’s 1.1.1.1 service Cloudflare have been running an open public DNS resolver service on…
The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If…
If you had the opportunity to re-imagine the DNS, what might it look like? Normally this would be an idle topic of speculation over a beer or two, but maybe there’s a little more to the question these days. We are walking into an entirely new world of the DNS…
