calidns — A DNS recursor testing tool

Synopsis

calidns QUERY_FILE DESTINATION INITIAL_QPS HITRATE

Description

calidns reads queries from QUERY_FILE and sends them as a recursive query to DESTINATION (an IPv4 or IPv6 address, optionally with a port number), starting at INITIAL_QPS queries per second and aims to have a cache hitrate of HITRATE percent.

It will then try to determine the maximum amount of queries per second the recursor can handle with the aforementioned HITRATE.

QUERY_FILE format

The format of the QUERY_FILE is very simple, it should contain "QNAMEQTYPE" tuples, one per line. For example:

powerdns.com A powerdns.com AAAA google.com A

This is similar to Alexa top 1 million list.
