about dns lookup

Query DNS records for any domain — including A, AAAA, MX, TXT, NS, CNAME, and SOA records — to inspect how a domain is configured.

The Domain Name System (DNS) is the internet's phonebook, translating human-readable domain names into IP addresses and other records that computers use to route traffic. This tool lets you query any domain's DNS records directly, giving you visibility into how a domain is configured at the DNS level.

You can look up A records to find IPv4 addresses, AAAA records for IPv6, MX records to see mail server configuration, TXT records for SPF/DKIM/DMARC verification, NS records for nameserver delegation, CNAME records for aliases, and SOA records for zone authority information.

This is invaluable for developers and system administrators who need to verify DNS propagation after making changes, troubleshoot email delivery issues by checking MX records, or confirm that domain verification TXT records are properly set up for services like Google Workspace or SSL certificate validation.

The lookup is performed server-side using real DNS resolution, providing accurate results that reflect the current state of the domain's DNS configuration. Results can be copied to your clipboard for documentation or sharing with your team.
