Repository Details

A fast and accurate DNS resolver written in Rust.

Rusolver

Fast DNS resolver written in Rust. Works on Linux, Windows, macOS, Android, Aarch64, ARM and possibly in your oven.

Goal

Offer the community an efficient host resolution tool.

Performance, speed and accuracy

Rusolver is very resource friendly, you can use up to 1000 threads in an single core machine and this will work without any problem, the bottleneck for this tool is your network speed. By default, Rusolver is able to perform resolution for ~1532 hosts per second in good network conditions (tested in an AWS machine). Additionally the tool does a double-check by default for resolved hosts against Cloudflare, Google, Quad9, OpenDNS, Verisign, UncensoredDNS and dns.watch DNS, with that algoritm the possibility to get an false-positive is null.

Demo

The files used in the demo are here. hosts.txt is the list of hosts to perform resolution and the resolved.txt are the ones that Rusolver found as active.

Using the AUR packages. (Arch Linux)

rusolver can be installed from available AUR packages using an AUR helper. For example,

If you prefer, you can clone the AUR packages and then compile them with makepkg. For example,

git clone https://aur.archlinux.org/rusolver.git && cd rusolver && makepkg -si

Usage

  • By default we only show the resolved hosts
cat hosts.txt | rusolver
  • If you want to see the discovered IP addresses:
cat hosts.txt | rusolver -i

You can tune the --timeout and -t/--threads options according to your needs. See rusolver --help
