WHOIS Lookup
Look up registration details for any domain or IP address. Powered by RDAP — the modern WHOIS replacement.
What WHOIS / RDAP tells you
For a domain: registrar, registration and expiry dates, name servers, DNSSEC status, and (where available) registrant and abuse contact information.
For an IP: the allocated range, parent network, country, organization, and abuse contact for that block. Useful for reporting abuse, identifying network operators, and verifying allocation legitimacy.
