How DNS.NF Works

What to use it for and how to read results

What It Does

Lookup DNS records for domains and IPs in one place.

Typical Use Cases

Propagation checks, mail troubleshooting, and DNS debugging.

Service Scope

Fast lookup, grouped results, copy actions, and raw JSON.

Data Completeness

Only publicly resolvable DNS data is returned.

DNS.NF queries only publicly available DNS data. We do not access private/internal DNS zones, and query targets are processed only to return lookup results.
