WHOIS / RDAP Lookup

Look up domain registration data using RDAP. The modern, structured replacement for legacy WHOIS. Returns registrar, creation/expiry dates, name servers, status flags, and the abuse contact. Useful for incident response, brand-protection investigations, and confirming a domain isn't about to expire on you.

Queries the appropriate registry's RDAP server (per IANA's bootstrap registry). ccTLDs without RDAP (such as .sk, .de, .fr) fall back to a legacy WHOIS lookup over port 43.

Why RDAP, not WHOIS

WHOIS (port 43) returns free-form text that varies per registrar. Impossible to parse reliably. RDAP (RFC 7480-7484) returns structured JSON with consistent field names: events.registration, entities[role=registrar], nameservers[].ldhName, etc. ICANN-mandated all gTLD registries to provide RDAP by 2019; most ccTLDs have followed. For the legacy ccTLDs that are still WHOIS-only (.sk, .de, .fr, and others), we fall back to a port-43 WHOIS query and show the raw text plus a best-effort parse, since those fields are not standardized.
