DNS Record Lookup

A client-side DNS lookup tool that queries public DNS servers to visualize A, MX, TXT, CNAME, NS, SOA, and CAA records for any domain in real-time. Perfect for developers checking DNS propagation, sysadmins troubleshooting email delivery, or security professionals auditing domain configurations. Stop waiting for command-line dig results and see what the world sees instantly. Works entirely in your browser by querying Cloudflare's DNS-over-HTTPS API, ensuring fast and secure lookups without installing software. Use DNS Lookup when you need answers fast during debugging, reviews, or incident triage. Paste your input, validate the output, then copy results into tickets or docs in seconds. Most processing runs in your browser, so you can test safely without unnecessary data exposure.

This tool queries Cloudflare's public DNS-over-HTTPS service to perform lookups. No API key is required. Your queries are sent to cloudflare-dns.com.

How to Use This Tool

  1. Enter Domain - Type the domain name you want to query (e.g., example.com)
  2. Select Record Types - Choose which DNS record types to lookup (A, MX, TXT, CNAME, etc.)
  3. Click Lookup - View all matching DNS records with TTL values and organized by record type

Why This Method?

Traditional DNS lookups require command-line tools like dig or nslookup, which aren't accessible on all devices. This tool uses DNS-over-HTTPS (DoH) to query Cloudflare's 1.1.1.1 resolver directly from your browser, providing the same authoritative results as dig but with a visual interface.

Different record types serve different purposes: A records map domains to IPv4 addresses, MX records handle email routing with priority values, TXT records store verification strings for services like Google Workspace, and CNAME records create domain aliases. Understanding these records is essential for domain management, email configuration, and SSL certificate validation.

By querying public DNS servers, you see the same records that visitors worldwide see, making this tool invaluable for verifying DNS propagation after domain changes or diagnosing why email isn't being delivered.
