What information does WHOIS provide?
WHOIS shows the available data about the owner of the resource: name, organization and contact details (unless they are hidden). This helps you contact the domain administrator or check who owns it.
Information about the registrar company through which the domain or IP address was registered. This matters for managing the domain, renewing it or transferring it to another service.
The domain's registration and expiry dates. Checking them helps you avoid losing the domain name and renew the registration on time.
WHOIS contains information about the name servers that serve the domain. They are needed for the website, email and other online services to work correctly.
Shows the current status of the domain: active, locked, expired, pending deletion or restricted from transfer. This helps you judge whether the domain can be used or re-registered.
Information obtained through WHOIS may be partly or fully hidden by privacy settings (WHOIS Privacy). In such cases, contact the registrar or the domain owner directly for the full registration data.
