DNStrace
forked https://github.com/redsift/dnstrace
Command-line DNS benchmark tool built to stress test and measure the performance of DNS servers with commodity hardware. This tool typically consumes ~30kB per concurrent connection and can maintain ~30,000 QPS per modern core if your server, OS and network allows you to reach suitable levels of concurrency.

Usage
$ dnstrace --help
usage: dnstrace [<flags>] <queries>...
A high QPS DNS benchmark.
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-s, --server="127.0.0.1" DNS server IP:port to test. IPv6 is also supported, for example '[fddd:dddd::]:53'.
-t, --type=A Query type.
-n, --number=1 Number of queries to issue. Note that the total number of queries issued = number*concurrency*len(queries).
-c, --concurrency=1 Number of concurrent queries to issue.
-l, --rate-limit=0 Apply a global questions / second rate limit.
--query-per-conn=0 Queries on a connection before creating a new one. 0: unlimited
-e, --expect=EXPECT ... Expect a specific response.
-r, --recurse Allow DNS recursion.
--probability=1 Each hostname from file will be used with provided probability in %. Value 1 and above means that each hostname from file will be used by each concurrent benchmark
goroutine. Useful for randomizing queries across benchmark goroutines.
--edns0=0 Enable EDNS0 with specified size.
--ednsopt="" code[:value], Specify EDNS option with code point code and optionally payload of value as a hexadecimal string. code must be arbitrary numeric value.
--tcp Use TCP fot DNS requests.
--dot Use DoT for DNS requests.
--write=1s DNS write timeout.
--read=4s DNS read timeout.
--codes Enable counting DNS return codes.
--min=400µs Minimum value for timing histogram.
--max=4s Maximum value for histogram.
--precision=[1-5] Significant figure for histogram precision.
--distribution Display distribution histogram of timings to stdout.
--csv=/path/to/file.csv Export distribution to CSV.
--io-errors Log I/O errors to stderr.
--silent Disable stdout.
--color ANSI Color output.
--version Show application version.
Args:
<queries> Queries to issue. Can be file referenced using @<file-path>, for example @data/2-domains
Warning
While dnstrace is helpful for testing round trip latency via public networks,
the code was primarily created to provide an apachebench
style tool for testing your own infrastructure.
It is thus very easy to create significant DNS load with non default settings. Do not do this to public DNS services. You will most likely flag your IP.
