About this DNS checker

This tool lets you query common DNS record types across multiple public resolvers (Google, Cloudflare, Quad9) with automatic fallback. It's designed to work without restrictions – just open the page and start using it.

If you ever encounter CORS issues, the simplest fix is to run a local web server:

• Python 3: python -m http.server 8000 then open http://localhost:8000/
• Node.js: npx serve
• VS Code: install Live Server extension and click "Go Live"

All record data is shown in blue for better readability, with compact table rows and word wrapping for long values like TXT records.
