Flamethrower is a new DNS performance and functional testing utility. Originally envisioned as an “improved dnsperf” and allowing simulation of realistic looking traffic patterns it has become a versatile tool for DNS server development and load testing. We will discuss motivations for its existence, its technical architecture, and use cases.

Knot DNS is a high-performance authoritative-only modern open-source DNS server. In this talk Knot DNS will be presented we will present the motivation, the goals and the current state of the project.

The Knot DNS supports most of the DNS standards and it has been already deployed at several TLDs and DNS hosters. Deployment at two root servers are already planned in upcoming months as an alternative to Bind 9 and NSD. The goal of the presentation is to show the audience the alternative DNS server that can be used to increase code diversity of used DNS software on the Internet.
