DNS Lookup

Resolve DNS records to validate domains and mail routing.

Resolve DNS records for any domain. Check A, AAAA, MX, TXT, NS, SOA, and CNAME records to verify your DNS configuration, troubleshoot mail delivery, or audit domain settings.

/tools/dns-lookup

How It Works

The domain and record type are sent to our server, which performs a DNS query using PHP's built-in dns_get_record() and returns the results. This uses the system's resolver and reflects the current global DNS state.

Frequently Asked Questions

This tool supports A, AAAA, MX, TXT, NS, SOA, and CNAME record types.
DNS results depend on the resolver. Our server uses its system resolver which may have different caching or see different propagation status than your local DNS.
Query MX records to confirm your mail server is correctly configured, and TXT records to check SPF/DKIM entries.
