What Is a WHOIS / RDAP Lookup?

Every registered domain has public registration data held by its registry. This tool looks it up - using the modern RDAP protocol where available and classic WHOIS as a fallback - and shows the registrar, registration date, expiry date, status codes and nameservers.

When to Use It

To check when a domain was registered or when it expires.
To find which registrar manages a domain before transferring it.
When investigating a suspicious or look-alike domain.

How to Use It

Enter the domain without http:// or paths.
Review the registrar, dates and status.

Understanding the Result

Status codes such as clientTransferProhibited are normal locks that prevent unauthorised transfers. redemptionPeriod or pendingDelete means the domain has expired and may soon be released.

Limitations

Since GDPR, owner names, emails and addresses are usually redacted. Some country-code TLDs provide limited data or none. Check privacy protection with the WHOIS Privacy Checker.

`serverHold`	Suspended by the registry; the domain does not resolve

Why Owner Details Are Often Hidden

Since GDPR (2018), most registrars redact personal contact details or show a privacy service instead. To reach an owner, use the registrar's contact form or the email relay address shown in the record.

For the registration date alone, try the Domain Age Checker; for a clean structured view, use the RDAP Lookup. Our guide how to find a domain owner explains more.

Frequently Asked Questions

Since 2018 (largely driven by GDPR), most registrars automatically redact personal registrant contact information from public WHOIS by default - this is standard, expected privacy protection, not a sign of anything suspicious about the domain.

RDAP is the modern, structured-data replacement for the older WHOIS protocol, offering standardized, machine-readable responses - many registries now prefer or require RDAP, though WHOIS remains widely supported as a fallback.

Registry and registrar systems can have their own propagation/sync delays for updating public WHOIS records - a very recent change may not be immediately reflected.

If the registrant has opted out of privacy redaction, an admin/technical contact email is sometimes listed - but with privacy redaction now the default for most registrars, a registrar-provided contact form is often the only available route.

Status codes like clientTransferProhibited or serverHold indicate registry/registrar-level locks or holds on the domain - clientTransferProhibited is common and simply means transfer-to-another-registrar is locked (usually intentionally, to prevent unauthorized transfers).

No - each top-level domain's registry operates its own WHOIS/RDAP server with its own data formatting and privacy policy, which is why lookups can look different for a .com versus a country-code TLD like .in or .co.uk.
