Purpose

This repository provides source code for the "DNS Privacy in Practice and Preparation" accepted at CoNEXT'19 and is meant to aid reproducibility of the study.

Code

All code was written for python3.

There is a common pattern of *_issuer.py and *_parser.py files. In these instances, the issuer was used to send queries and run a tcpdump subprocess that was recording incoming queries. The parser was then run on the pcap. This was necessary in cases where sequential packets needed to be grouped (such as TFO) or cases where the incoming pcap was recorded from an authoritative server over an interface.

Dependencies

Some code relies on a fork of dnspython which provides added support for DoT and DoH. This fork can be found here

All other dependencies are publicly available.
