🌐 A continuously updated list of high-quality DNS resolvers, validated daily.

📖 Overview

This repository maintains a curated list of public DNS resolvers that have been verified to be stable, responsive, and returning validated results. The resolver list is updated every 24 hours through an automated pipeline.

🔬 Methodology

Our validation process combines multiple techniques to ensure only reliable resolvers make it into the list:

  • 🔗 Aggregation — Resolvers are pulled from over 100 different public sources and merged into a single deduplicated list.
  • 📡 Port Scanning — We continuously scan for open port 53 (DNS) across the IPv4 space 24/7 to discover new resolvers as they come online.
  • ⏱️ Stability Testing — Each discovered resolver is tested repeatedly over time. Only resolvers that demonstrate consistent uptime and response times are included.
  • Response Validation — Resolvers must return correct, non-poisoned responses for a set of known domains. Any resolver returning invalid or manipulated results is removed.
  • 🔄 Daily Refresh — The entire list is regenerated daily, dropping any resolvers that have gone offline or started misbehaving.

🚀 Usage

Fetch the latest resolver list directly:

curl -sL https://raw.githubusercontent.com/acidvegas/liveresolvers/main/resolvers.txt

Or clone the repository:

git clone https://github.com/acidvegas/liveresolvers.git

🔒 Privacy-Focused Resolvers

For users who prefer well-known, privacy-respecting DNS providers, we also maintain a separate privacy-resolvers.txt file. This includes providers like Cloudflare, Quad9, Mullvad, AdGuard, NextDNS, and others that have strong no-logging policies and support encrypted DNS protocols (DoH/DoT).

📄 Format

The resolvers.txt file contains one IPv4 address per line — no ports, no comments, no extra formatting. Ready to use with tools like massdns, dnsx, puredns, shuffledns, etc.
