About Domain Registration Status Checker
WHOIS is the public protocol for looking up who registered a domain name, when it was registered, when it expires, and which registrar and name servers manage it. It's one of the oldest parts of internet infrastructure, predating the modern web, and remains the standard way to check a domain's registration status.
This tool performs a real WHOIS lookup by first querying IANA (the internet's central registry authority) to find which registry is authoritative for the domain's top-level extension (.com, .org, .io, and so on), then querying that specific registry's WHOIS server directly — exactly how a proper WHOIS client is supposed to work, rather than just guessing a fixed server.
Since privacy regulations like GDPR took effect, many registrars now redact personal registrant details (name, email, address) by default, showing the registrar's privacy proxy service instead. Registration dates, expiry dates, name servers, and registrar information typically remain visible even with privacy protection enabled.
This is useful for checking when a domain expires (important before it lapses and becomes available for anyone to register), verifying who currently owns a domain before a purchase negotiation, confirming a domain transfer completed correctly, and general domain research.
How it works
- Enter a domain name. Any registered domain, without http:// or www.
- Click Lookup. Queries IANA for the authoritative registry, then that registry's WHOIS server.
- Review the raw record. The full WHOIS response is shown exactly as the registry returns it.
