WHOIS domain lookup
Check who registered a domain, when it expires, its nameservers, and DNSSEC status using RDAP, the modern WHOIS protocol.
Look up domain registration details
Powered by RDAP, the structured successor to port-43 WHOIS. Registrant contact details are redacted by registries under GDPR.
WHOIS, modernised as RDAP
Registration data tells you a domain's registrar, key dates, and nameservers, which is useful when you plan a migration, chase an expiry, or vet a domain. This tool uses RDAP, the structured JSON successor to port-43 WHOIS that registries are required to support.
What this tool gives you
- Registrar, registration, last-changed, and expiry dates for a domain.
- Nameservers, domain status codes, and DNSSEC signing state.
- A clear signal when a domain looks unregistered and may be available.
