Rusolver

Fast DNS resolver written in Rust.

Goal

Offer the community an efficient host resolution tool.

Performance & speed

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 ~1226 hosts per second in good network conditions (tested in an AWS machine).

#
# hosts.txt is a list of 61309 Google subdomains. See https://gist.github.com/Edu4rdSHL/90ddc4742b816439a112a95039a95312

Usage

  • By default we only show the resolved hosts

  • 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
