NS1, the leader in next-generation DNS and traffic management solutions, announced the availability of Flamethrower, a lightweight, configurable open source tool for functional testing, benchmarking, and stress testing DNS servers and networks. Flamethrower is available on GitHub.
Flamethrower is a small, fast, configurable tool for functional testing, benchmarking, and stress testing DNS servers and networks. It supports IPv4, IPv6, UDP and TCP, and has a modular system for generating queries used in the tests.
It was built as an alternative to dnsperf (https://nominum.com/measurement-tools/), and many of the command line options are compatible.
