What is WHOIS lookup?

WHOIS lookup is a query tool that retrieves publicly available registration data for a domain name, including the registrar, owner contact details (when not redacted by GDPR), registration date, expiry date, and nameservers.

Is the WHOIS lookup tool free?

Yes. Netislem's WHOIS lookup tool is completely free. You can query any domain name at any time without creating an account.

Why is owner information hidden in WHOIS results?

GDPR and similar privacy regulations allow domain registrars to redact personal contact information from public WHOIS records. This is standard practice for .com, .net, .org and most ccTLD domains. The technical data (nameservers, dates, registrar) is still publicly visible.

What is RDAP and how is it different from WHOIS?

RDAP (Registration Data Access Protocol) is the modern successor to the legacy WHOIS protocol. It returns structured JSON data and supports internationalised domain names. Netislem's tool uses RDAP for accurate, up-to-date results wherever available.
