Counting IPv6 in the DNS

At the recent ARIN XXX meeting in October 2012 I listened to a debate on a policy proposal concerning the reservation of a pool of IPv4 addresses to address critical infrastructure. The term “critical infrastructure” is intended to cover a variety of applications, including use by public Internet Exchanges and…


Re-counting DNSSEC

This is a followup article to “Counting DNSSEC” that reflects some further examination of the collected data. This time I’d like to describe some additional thoughts about the experiment, and some revised results in our efforts to count just how much DNSSEC is being used out there. And for those…


Counting DNSSEC

At the Nordunet 2012 conference in September, a presentation included the assertion that “more than 80% of domains could use DNSSEC if they so chose.” This is an interesting claim that speaks to a very rapid rise in the deployment of DNSSEC in recent years, and it raises many questions…


IPv4 The Movie – The Directors’ Cut

Back in 2005 we were looking for a way to visualise the history of allocation of IPv4 addresses, and one of the approaches we tried at the time was in the way of a movie. In this visualisation we included the data for the allocation of IPv4 addresses, Autonomous System…


Leaping Seconds

The tabloid press are never lost for a good headline, but this one in particular caught my eye: “Global Chaos as moment in time kills the Interwebs“. I’m pretty sure that “global chaos” is somewhat over the top, but there was a problem happening on the 1st of July this…


Carriage vs Content

Does anyone remember the Internet before Google? And no, using Google to ask about the pre-Google Internet is not going to work all that well! For those of you who can recall the Internet of around 2000, do you also recall what debates were raging at the time? Let me…


Measuring IPv6 – Country by Country

Some years ago a report was published that ranked countries by the level of penetration of broadband data services. You can find the current version of that report at the OECD web site.This ranking of national economies had an electrifying impact on this industry and upon public policies for broadband…


Occam’s ITRs

It’s been a quarter of a century since the world’s governments convened to draft up a common set of regulations about the conduct of international telecommunications. In December of 2012 the world’s governments will convene to reconsider these regulations, to hopefully sign an updated set of regulations. This time around,…


The QoS Emperor’s Wardrobe

Back in 1997, with Paul Ferguson, I wrote a book on “Quality of Service” (QoS) in IP networks. A couple of years later I pushed out a revision of the book (“Internet Performance Survival Guide”) that looked more generally at service performance in IP networks, and examined in voluminous detail…
