WHOIS has traditionally been the way to look up who registered a domain and when. This tool uses RDAP — WHOIS's modern, structured successor — to pull live registration data directly from the authoritative registry, covering registrar, key dates, nameservers, status codes and DNSSEC.

Understanding your results
Registration and expiry dates help you spot domains at risk of lapsing — an expiring domain within 30 days is flagged. Status codes like clientTransferProhibited are normal security locks, not problems. Registrant contact details are almost always redacted under registry privacy policies now (GDPR and similar) — this tool never claims to reveal ownership details that the registry itself keeps private.
Frequently asked questions
What is WHOIS?
WHOIS is the long-standing protocol and database system used to look up who has registered a given domain name, along with registration dates and technical details like nameservers.
Why can't I see the domain owner's contact details?
Almost all registries now redact registrant contact information by default under privacy regulations such as GDPR. This is standard, expected behaviour across the industry — not a limitation specific to this tool.
What is RDAP and how is it different from WHOIS?
RDAP (Registration Data Access Protocol) is the modern, structured, JSON-based successor to classic WHOIS, designed to be easier for tools and browsers to query directly and reliably. This tool uses RDAP under the hood.
