DNS Lookup

Resolve a domain's DNS records — A, AAAA, MX, NS, TXT, SRV, CAA, SOA — in one query, over fast DNS-over-HTTPS.

What is a DNS record?

The entries that map a domain to addresses, mail servers, and policy.

DNS records are the entries that make a domain work. A / AAAA point the name at IPv4 / IPv6 addresses; MX names the mail servers (with a priority); NS lists the authoritative nameservers; TXT holds free-form policy (SPF, DKIM, domain verification); CAA says which certificate authorities may issue for the domain; SOA carries the zone's serial and timers; SRV advertises services on specific ports (queried as _service._proto.domain).

This lookup runs server-side over DNS-over-HTTPS (Cloudflare), querying all record types in parallel, with a native resolver fallback. Browsers can't make raw DNS queries, so the work happens on our server — your input never goes anywhere else.

Frequently asked

What is the difference between an A and AAAA record?

An A record maps a hostname to an IPv4 address; an AAAA record (said 'quad-A') maps it to IPv6. A domain can publish both, and clients use whichever they support.

What is an MX record?

A mail-exchange record tells other servers where to deliver email for the domain, each with a priority number — lower is preferred. No MX record means the domain cannot receive email.

Why don't my DNS changes show up yet?

Records are cached for their TTL (time-to-live). This tool queries fresh over DNS-over-HTTPS, but resolvers elsewhere may keep serving the old answer until the TTL expires.
