DNS lookup

Check the public DNS records for a domain. Choose a record type to inspect its addresses, mail servers, verification records or nameservers.

Good to know

What do the different record types mean?+

A and AAAA point to IPv4 and IPv6 addresses. MX identifies mail servers, TXT stores text such as SPF or verification values, and NS identifies authoritative nameservers. CNAME is an alias, SOA describes a zone, and CAA limits certificate issuers.

Why do I still see an old DNS record?+

Resolvers cache records according to their TTL. A change becomes visible as existing cached answers expire. Different resolvers can temporarily return different answers.
