DNS Privacy (by Geoff Huston)

18/07/2016

The DNS is normally a relatively open protocol that smears its data (which is your data and mine too!) far and wide. Little wonder that the DNS is used in many ways, not just as a mundane name resolution protocol, but as a data channel for surveillance and as a common means of implementing various forms of content access control. But all this is poised to change. Now that the Snowden files have sensitized us to the level of such activities, we have become acutely aware that many of our tools are just way too trusting, way too chatty, and way too easily subverted. First and foremost in this collection of vulnerable tools is the Domain Name System.
