- 2
Pick record types
Leave All types to query A, AAAA, CNAME, MX, TXT, NS, SOA and CAA together, or choose a single type.

Read the answers
Each type lists its records with TTLs, mail priorities or zone timers, or says clearly why there is no answer.
Limits and Pro
Free: 20 lookups a minute, up to 8 record types per lookup, a 3-second timeout with 2 tries per query and 8 seconds overall.
About DNS lookup
This DNS lookup has our server ask public resolvers, Cloudflare's 1.1.1.1 and Google's 8.8.8.8, for the records published for a domain, and shows them grouped by type. It answers the everyday questions behind a launch or a migration: does the name point to the new server (A and AAAA), is www an alias of something else (CNAME), which servers accept its mail and in what order (MX), are SPF, DKIM, DMARC and verification strings in place (TXT), which name servers are authoritative (NS, SOA), and which certificate authorities may issue certificates (CAA).
Internationalised names are converted to their punycode form, so bücher.example works, and a pasted URL is reduced to its host. A public IPv4 or IPv6 address returns its reverse DNS (PTR) name, which mail servers often check. Errors are spelled out: a domain that doesn't exist (NXDOMAIN) is distinguished from one that simply has no records of the type you asked for, a server failure or a timeout.
Results reflect what those public resolvers see right now and may come from their caches for up to each record's TTL. The lookup doesn't query each authoritative server separately, trace delegation or check DNSSEC, and names that only exist on private networks, such as .local or .internal, are refused.
Privacy
The name you enter is sent to our server, which asks public DNS resolvers (1.1.1.1 and 8.8.8.8) for its records and returns the answer to your browser; neither the name nor the result is stored or logged.
