It’s time I updated the IPv4 Address Report. For ARIN and LACNIC the time when the registry reaches into its collection of available IPv4 addresses and comes out empty handed is getting closer, and its time to sharpen up the modelling about exhaustion.
One IP address is much the same as another – right? There’s hardly a difference between 192.0.2.45 and 192.0.2.46 is there? They are just encoded integer values, and aside from numerological considerations, one address value is as good or bad as any other – right? So IP addresses are much…
One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus. How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and…
At the April 2013 ARIN meeting the inevitable question came up once more: “Exactly when is ARIN going to run out of IPv4 addresses?” Various dates have been proposed as an answer to this question, based on various methods of prediction. As the date is indeed getting closer, it may…
For some time now we’ve been tracking the progress of the deployment of DNSSEC in the Internet. Its been a story of an evolution of the measurement technique, starting with a technique that attempted to guess at the behaviour of resolvers, through to techniques that explicitly pose novel DNS names…
Much has been said in recent weeks about various forms of cyber spying. The United States has accused the Chinese of cyber espionage and stealing industrial secrets. A former contractor to the United States’ NSA, Edward Snowden, has accused various US intelligence agencies of systematic examination of activity on various…
On the 6th June 2012 we held the World IPv6 Launch Day. Unlike the IPv6 event of the previous year, World IPv6 Day, where the aim was to switch on IPv6 on as many major online services as possible, the 2012 program was somewhat different. This time the effort was…
This story started earlier this year, with a posting to the Australian network operators’ mailing list, asking if anyone had more information about why the web site that was operated by an outfit called “Melbourne Free University†was inaccessible through a number of major Australian ISPs. When they asked their…
For some years now at APNIC Labs we’ve been conducting a measurement exercise intended to measure the extent to which IPv6 is being deployed in the Internet. This is not a measurement of IPv6 traffic volumes, nor of IPv6 routes, nor of IPv6-capable servers. This is a measurement of the…
For some time now at APNIC Labs we’ve been running an experiment that is intended to measure the state of IPv6 capability across the Internet. To do this we use a number of experimental data sources. A number of web site administrators have kindly put our Javascript test code on…
