       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.
