DNS Lookup

Query A, AAAA, MX, TXT, NS and CNAME records for any domain

What is DNS Lookup?

A DNS lookup tool queries the Domain Name System to retrieve all DNS records for a domain. DNS translates human-readable domain names into IP addresses and configures email delivery (MX), domain verification (TXT), nameserver delegation (NS) and aliases (CNAME).

How to Use DNS Lookup

  1. 1

    Enter a domain

    Type a domain like google.com or example.org.

  2. 2

    Click Lookup

    We query all 6 record types (A, AAAA, MX, TXT, NS, CNAME) in parallel.

  3. 3

    Review records

    Each record type is shown in its own section with record count and description.

  4. 4

    Copy results

    Copy all DNS records in a formatted text block.

Features

  • Queries 6 record types simultaneously
  • MX records with priority ranking
  • TXT records (SPF, DKIM, verification)
  • NS nameserver listing

Frequently Asked Questions

What are A records?+
A records map a domain name to an IPv4 address. They tell browsers which server to connect to when visiting your website.
What are MX records?+
MX (Mail Exchange) records specify which mail servers accept email for your domain. Lower priority numbers have higher precedence.
What are TXT records used for?+
TXT records store text data for domain verification (Google, Microsoft), email authentication (SPF, DKIM, DMARC) and other purposes.
Why are my DNS changes not showing?+
DNS changes can take up to 48 hours to propagate globally due to caching at various DNS resolver levels. Most changes propagate within 1-4 hours.
