The Internet’s Domain Name System is a modern day miracle. It may not represent the largest database that has ever been built, but nevertheless it’s truly massive. And even if it’s not the largest database that’s ever been built, it’s perhaps one of the more intensively used. The DNS is…
Yes, that’s a cryptic topic, even for an article that addresses matters of the use of cryptographic algorithms, so congratulations for getting even this far! This is a report of a an experiment conducted in September and October 2014 by the authors to measure the extent to which deployed DNSSEC-validating…
If you’re playing in the DNS game, and you haven’t done so already, then you really should be considering turning on security in your part of the DNS by enabling DNSSEC. There are various forms of insidious attack that start with perverting the DNS, and end with the misdirection of…
At APNIC Labs we’ve been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP.
Much has been said about how Google uses the services they provide, including their mail service, their office productivity tools, file storage and similar services, as a means of gathering an accurate profile of each individual user of their services. The company has made a very successful business out of…
It was never obvious at the outset of this grand Internet experiment that the one aspect of the network’s infrastructure that would truly prove to be the most fascinating, intriguing, painful, lucrative and just plain confusing, would be the Internet’s Domain Name System.
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…
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…
There are a number of reasons that both domain name administrators and vendors of client DNS software cite for not incorporating DNSSEC signing into their offerrings. The added complexity of the name administration process when signatures are added to the mix, the challenges of maintaining current root trust keys, and…
The Domain Name System, or the DNS, is a critical, yet somewhat invisible component of the Internet. The world of the Internet is a world of symbols and words. We invoke applications to interact with services such as Google, Facebook and Twitter, and the interaction is phrased in human readable…
