DNS Tester

DNS Tester is a command-line tool written in Go that benchmarks various DNS providers by measuring key performance metrics such as ping latency, jitter, DNS resolution time, and packet loss. It then computes a composite score based on these metrics and recommends the top-performing providers for fast and consistent DNS resolution.

Features

• Comprehensive Metrics: Computes average, median, minimum, maximum, and jitter for both ping and DNS resolution.
• Packet Loss Detection: Measures packet loss to evaluate the reliability of each provider.
• Composite Scoring: Uses a weighted composite score to rank DNS providers.
• Cross-Platform: Works on Linux, macOS, and Windows.
• CI/CD Integration: Automatically builds and releases binaries via GitHub Actions.

Requirements

• Go 1.24 or later
• The following commands must be available on your system:
  • ping for latency tests
  • dig for DNS resolution tests

Run

Linux / MacOS:

curl -L "https://raw.githubusercontent.com/hawshemi/dns-tester/main/dns-tester-run.sh" -o dns-tester-run.sh && chmod +x dns-tester-run.sh && bash dns-tester-run.sh

Windows: (Broken for now)

1. Download from Releases.
2. Open CMD or Powershell in the directory.

3. .\dns-tester.exe
   

Usage

Flags:

--output (-o): Output format (table, json, csv), default: table

--runs (-r): Number of test runs, default: 3

--help (-h): Show help

Examples:

./dns-tester
./dns-tester -o json -r 5
./dns-tester --output=csv --runs=2
