NAME

       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

       --ecs <SUBNET>
              Add EDNS Client Subnet option to outgoing queries using random addresses from the specified SUBNET
              range (IPv4 only).

       --ecs-from-file
              Read IP or subnet values from the query file and add them as EDNS Client Subnet option to outgoing
              queries.

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

       --maximum-qps <NUM>
              Stop incrementing once this rate has been reached, to provide a stable load.

       --minimum-success-rate <NUM>
              Stop the test as soon as the success rate drops below this value, in percent.

       --plot-file <FILE>
              Write results to the specified file.

       --quiet
              Whether to run quietly, outputting only the maximum QPS reached.  This  option  is  mostly  useful
              when used with --minimum-success-rate.

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