Frequently Asked Questions
What is WHOIS and why is it useful?
WHOIS is a public database that stores information about domain name registrations, including the registrar, registration and expiry dates, name servers, and status codes. It helps verify domain ownership, check when a domain expires, and investigate potential trademark or fraud issues.
Why is some registrant information hidden?
Due to privacy regulations like GDPR and ICANN's temporary specification, most registrars redact personal data (name, email, phone, address) from public WHOIS output. Only the registrar name and dates are typically visible for most domains.
What does RDAP mean 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 internationalization, and provides more reliable access to registration data. All generic top-level domains (gTLDs) are required to support RDAP.
