WHOIS Lookup

What is WHOIS Lookup?

WHOIS is the public registry record for a domain name — it shows who registered it (where not redacted by privacy protection), which registrar it's registered through, when it was created, when it expires, its current status, and which nameservers it delegates to.

This is the standard first step when investigating domain ownership, checking expiry before a renewal lapses, or verifying the legitimacy of a domain before doing business with it.

How to use the WHOIS Lookup tool

1 Enter the domain name you want to look up, e.g. example.com (no need for http:// or www).
2 Run the lookup and review the registrar, creation date, and expiry date.
3 Check the domain status codes (like clientTransferProhibited or pendingDelete) to understand the domain's current lifecycle state.
4 Check the nameservers listed to confirm which DNS provider is actually authoritative for the domain.

When you need this tool

Checking when a domain you own is due to expire so you can renew it in time.
Researching who owns or operates a domain before a business transaction, acquisition, or dispute.
Confirming a domain transfer completed by checking the registrar field changed to the new provider.
Investigating a suspicious or phishing domain's registration date and registrar as part of a security review.
Verifying nameserver delegation after moving a domain to a new DNS provider.

How it works

The tool queries the WHOIS (or, for newer TLDs, RDAP) server that the domain's registry operator publishes, following the referral chain from the generic registry WHOIS server to the registrar's own WHOIS server where needed, and returns the record as published. Most registrant personal details are redacted by default under privacy/GDPR rules unless the domain owner has opted out of privacy protection.

Frequently asked questions

Why can't I see the domain owner's name and email?

Since GDPR and ICANN's updated privacy requirements, most registrars redact personal registrant details (name, email, address) by default, replacing them with the registrar's privacy proxy contact. Only organizational registrants, certain ccTLDs, or domains with privacy protection explicitly disabled will show full contact details.

What does "clientTransferProhibited" mean in the status field?

It's a standard EPP status code set by the registrar (often by default) that blocks the domain from being transferred to another registrar until it's removed. It doesn't affect how the domain resolves or functions — only the ability to move it between registrars.

Why does a domain's WHOIS show a different expiry date than I expect?

The registry expiry date reflects the current registration period on file, which can be ahead of a date you remember if auto-renewal already processed, or because the registrar locked in a multi-year term at purchase. Always treat the WHOIS expiry date as authoritative over your own records.

Can I use WHOIS to check if a domain is available to register?

A WHOIS lookup returning no record (or a clear "no match" response) generally indicates the domain is available, but availability should be confirmed directly with a registrar before assuming you can register it — some domains are reserved, in a redemption grace period, or in the process of being released.
