Frequently Asked Questions
What is a WHOIS lookup?
A WHOIS lookup retrieves publicly available registration information about a domain name, including the registrar, owner contact details (when not redacted), creation date, expiry date, nameservers, and domain status.
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, supports internationalized domain names, and provides more consistent, standardized responses across registries.
Why might some domain information be redacted?
Since GDPR and similar privacy regulations, many registrars redact personal contact information (name, email, phone) for privacy protection. Registrar, nameservers, dates, and status codes are typically still visible.
Which domain extensions does this tool support?
This tool supports most major TLDs and ccTLDs including .com, .net, .org, .io, .co, .uk, .de, and many more, as long as the domain's registry supports the RDAP protocol.
