Table of contents
This repository provides DNS benchmarking command line tool written in Rust. It iterates through built-in list of public DNS servers, measures their response time and print table with sorted results in console. It can be used to find the fastest DNS in your location for better internet browsing experience. An example of console output, list of features and list of built-in DNS servers can be found below.
- Built-in list of public DNS servers.
- Requests count configuration. By default, 25 requests are made to each DNS server.
- Threads count configuration. By default, 8 threads are used.
- Timeout configuration. By default, 3 seconds timeout is used.
- Domain configuration. By default, google.com domain is used.
- Protocol configuration, either TCP or UDP. By default, UDP is used.
- Lookup IP version configuration, either IPv4 or IPv6. By default, IPv4 is used.
- Configuration of IP version used to establish connection, either IPv4 or IPv6. By default, IPv4 is used.
- Table style configuration. By default, rounded style is used.
- Ability to save favorite configurations in a file inside user's home directory (
/home/user/.dns-bench/config.toml) to avoid typing them every time. - Ability to provide custom servers list instead of built-in list.

- If you don't have Rust programming language environment installed on your machine, then installation from Docker Hub will be the best option for you.
- If you have Rust programming language environment installed on your machine, then you can choose between installation from crates.io or installation from git repository.
- Installation from git repository is suitable only when you want to use the development version instead of the stable one or the crates.io service is unavailable.
Run the following command and wait until the crate is compiled:
$ cargo install dns-benchNow you can run compiled binary:
$ dns-bench [OPTIONS]Run the following command and wait until the crate is compiled:
$ cargo install --git https://github.com/qwerty541/dns-bench.git --tag v0.7.1 dns-benchAlso you can remove tag option to install the latest development version.
Now you can run compiled binary:
$ dns-bench [OPTIONS]Run the following command to pull the image:
$ docker pull qwerty541/dns-bench:0.7.1Now you can run this tool inside the container:
$ docker run --rm -it --name dns-bench qwerty541/dns-bench:0.7.1If you want to pass some options, you can do it like this:
$ docker run --rm -it --name dns-bench qwerty541/dns-bench:0.7.1 /bin/bash -c "dns-bench --requests 20 --domain microsoft.com --style re-structured-text"Below is a list of currently supported options.
