How to Use the DNS Lookup Tool

Enter a domain name and select the record type (or ALL). The tool queries Cloudflare's DNS-over-HTTPS API and displays results with record types, values, and TTL information.

Features

  • Multiple Record Types — Query A, AAAA, CNAME, MX, TXT, NS, or ALL at once.
  • Cloudflare DoH — Uses Cloudflare's privacy-focused DNS-over-HTTPS API.
  • TTL Display — Shows Time-To-Live values for each record.
  • Color-Coded Types — Each record type has a distinct color badge for easy scanning.
  • Copy Results — Export results in tab-separated format.

    • Common Use Cases

  • Domain Troubleshooting — Check if DNS records are configured correctly after changes.
  • Email Setup — Verify MX records point to the correct mail server.
  • SSL/TLS — Confirm CNAME records for certificate validation.
  • Migration Planning — Document existing DNS configuration before provider changes.

    • Why Use This Tool

    DNS propagation issues are one of the most common causes of website downtime. This tool lets you quickly verify records without memorizing dig or nslookup commands, and it works entirely in the browser.
