DNS Lookup Tool

Check common DNS records for a domain, including A, AAAA, MX, NS, TXT, CNAME, and SOA results.

A DNS lookup translates a domain name into the records published by its authoritative DNS system. Enter a domain to review the addresses, mail servers, nameservers, verification records, aliases, and zone details that are currently available.

This tool is useful when diagnosing website outages, email delivery problems, domain verification, nameserver changes, IPv6 configuration, and propagation questions. DNS answers may differ by resolver and can change as cached records expire.

What the record types mean

A records point a name to IPv4 addresses, while AAAA records point to IPv6 addresses. MX records identify mail servers, NS records identify authoritative nameservers, TXT records carry verification or policy text, CNAME records create aliases, and SOA records describe the DNS zone.

Why DNS results can change

DNS records have time-to-live values that control caching. After a change, some resolvers may continue returning an older answer until the cached record expires.

How to troubleshoot an empty result

Confirm that the domain is spelled correctly and delegated to working nameservers. Some record types are optional, so an empty section does not always indicate a problem.

Privacy and safe use

The lookup sends the domain to the server resolver and returns the resulting records. Avoid entering private internal hostnames that should not be exposed outside your organisation.

Frequently Asked Questions

What is a DNS lookup?

It is a request to retrieve one or more DNS records published for a domain name.

Why is my new record not visible yet?

Resolvers may still have the previous answer cached until its TTL expires.

Does every domain have all record types?

No. Domains publish only the record types they need.
