What is a WHOIS lookup?
A WHOIS lookup retrieves publicly available domain registration data, including the registrar, registration and expiry dates, authoritative name servers, and domain status.
WHOIS & domain data
Clear, up-to-date explanations of WHOIS and RDAP, what domain data is public, why details are hidden, and how to interpret registration records correctly.
A WHOIS lookup retrieves publicly available domain registration data, including the registrar, registration and expiry dates, authoritative name servers, and domain status.
No. WHOIS and RDAP lookups are read-only queries and do not affect domain ownership, DNS configuration, or registration status.
WHOIS typically provides registrar details, registration and expiry dates, name servers, domain status codes, and registry identifiers.
A registrar is an accredited company that registers domain names on behalf of customers and interacts with domain registries to manage records.
The registry operates the top-level domain itself, while registrars sell domain registrations and manage records for domain owners.
Privacy regulations and registry policies restrict the publication of personal data, so registrant names, addresses, and contact details are often redacted.
Yes. GDPR and similar regulations significantly reduced the amount of personal data published in WHOIS records for individual registrants.
WHOIS can identify the registrar and registration status, but personal ownership details are often unavailable or anonymised.
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS, providing structured, machine-readable domain registration data over HTTPS.
RDAP offers consistent formatting, better internationalisation, authentication support, and modern transport security compared to legacy WHOIS.
WHOIS data reflects what registries and registrars publish. While generally reliable, updates may take time depending on registry refresh cycles.
The expiry date indicates when a domain registration is scheduled to lapse if not renewed. Domains often enter grace periods before deletion.
Status codes describe registry or registrar restrictions, such as transfer locks, deletion holds, or suspension states.
Yes. WHOIS and RDAP data is public, but automation must respect registry rate limits and acceptable use policies.
Yes. Registries and RDAP servers enforce rate limits to prevent abuse and excessive automated querying.
No. Standard WHOIS and RDAP only show current registration data, not historical ownership changes.
Common misconceptions include assuming WHOIS shows private owners, that data is always complete, or that WHOIS can reveal website operators.
No. Velohost performs WHOIS and RDAP lookups live and does not store domains, results, or lookup history.
