calidns -
calidns - A DNS recursor testing tool
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.
