FAQ
What is WHOIS?
WHOIS is a protocol for querying domain registration information. It tells you who registered a domain, when it was created, when it expires, and which nameservers it uses.
What is RDAP?
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It returns structured JSON data and supports standardized access controls.
Why is registrant data redacted?
Since GDPR and ICANN's Temporary Specification, most registrars redact personal registrant data. This is normal and expected for privacy compliance.
What does the health score measure?
We score five categories: expiry proximity (is the domain about to expire?), domain age (how established is it?), registrar lock (transfer protection), DNSSEC (DNS security), and data completeness.
