Synopsis

calidns [Options] 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 “QNAME QTYPE” tuples, one per line. For example:

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

This is similar to Alexa top 1 million list.

Options

--increment <NUM>

On every subsequent run, multiply the number of queries per second by NUM. By default, this is 1.1.

--want-recursion

Set this flag to send queries with the Recursion Desired flag set.
