DNS lookup

Find out where a name leads.

Look up A, AAAA, MX, TXT, NS, CAA, SOA, PTR, CNAME, SRV, HTTPS, and SVCB records. Compare the DNS answers returned by Cloudflare and Google.

Resolver

International names are converted to ASCII (punycode) before querying. Enter names without a URL or path; service names such as _sip._tcp.example.com are supported. Comparing resolvers makes two requests. PTR accepts an IP or a reverse name. Queries go to your selected provider.

A query link contains the entered name and query settings; it contains no results or saved snapshot. Opening it does not run a lookup automatically.

Examples:

Read the difference, not just the status

Resolver comparisons list records unique to each response and records common to both. Snapshot comparisons show added and removed data. They ignore TTL drift, record ordering, name case, and equivalent IPv6 spellings. TXT values and unknown parameter values are preserved conservatively.

This reflects recursive DNS answers from our server’s location. It does not test worldwide propagation, your own DNS resolver, or whether a listed service is reachable.

Expand “Interpret record” to read MX preferences, SOA timings, SRV endpoints, CAA properties, HTTPS/SVCB parameters, and common email-policy text. Interpretations describe published data; they do not perform certificate, email, or service validation.

An unset AD flag can mean an unsigned domain; it is not by itself a DNSSEC failure. The overview covers the exact entered name, not all subdomains.
