Frequently Asked Questions
What is WHOIS?
WHOIS is a query protocol that provides registration information about domain names, including the registrar, creation and expiration dates, name servers, and registration status. Modern WHOIS uses RDAP (Registration Data Access Protocol) which returns structured, machine-readable data.
Is WHOIS lookup free?
Yes, WHOIS lookups are free. Domain registration data is publicly available through RDAP servers maintained by domain registries. Our tool queries rdap.org which routes requests to the correct registry automatically.
What information does WHOIS show?
WHOIS shows the domain registrar, creation date, expiration date, last update date, name servers, and registration status codes. Due to GDPR and privacy regulations, personal contact information of domain owners is often redacted.
