Enter a domain to propagate DNS records.

key Features

  • Fetch A, AAAA, MX, NS, TXT, and CNAME records
  • Verify mail server (MX) priorities for email delivery
  • Check nameservers (NS) to confirm hosting provider
  • Debug DNS propagation issues globally
  • Inspect SPF, DKIM, and verification records (TXT)

The Free DNS Lookup Tool acts as an online `nslookup` or `dig` command, providing a complete view of a domain's public DNS configuration. The Domain Name System (DNS) is the critical infrastructure that translates human-readable domain names into machine-readable IP addresses.

Common Use Cases:

  • Website Migration: Verify that your A Records have updated to point to your new web host's IP address.
  • Email Troubleshooting: Check your MX Records to ensure emails are being routed correctly and verify priorities.
  • Security Verification: Inspect TXT Records to confirm SPF, DKIM, and DMARC settings, which prevent email spoofing.

Our tool queries authoritative nameservers directly to ensure you are seeing the most up-to-date data available, bypassing local ISP caches that might show old information.

Frequently Asked Questions

What is DNS propagation?

When you change your DNS records (like moving hosting), it takes time for the changes to spread (propagate) across the internet. This can take anywhere from a few minutes to 48 hours depending on your TTL (Time to Live) settings.

What are MX records used for?

MX (Mail Exchange) records tell email servers where to deliver emails sent to your domain. If your MX records are missing or incorrect, you won't receive emails.

What is the difference between A and CNAME?

An **A Record** maps a domain directly to an IP address (e.g., 192.168.1.1). A **CNAME Record** points a domain to another domain name (e.g., 'www' points to 'example.com'). You cannot put a CNAME at the root (@) of your domain.

How do I check SPF records?

SPF records are stored as **TXT** records. Use our tool to lookup TXT records for your domain, and look for a value starting with `v=spf1`.
