How to Read a WHOIS Result
What information a domain WHOIS contains, what each field means and how to check expiry, registrar and nameservers.
What Is WHOIS?
WHOIS is a protocol (and database) that contains information about domain owners. Every registered domain creates a WHOIS record with contact details, dates, registrar and nameservers.
What a WHOIS Result Contains
| Field | Meaning |
|---|---|
| Registrant | The domain owner (name, email, phone — often masked due to GDPR) |
| Registrar | The company through which the domain was registered (GoDaddy, Namecheap, etc.) |
| Created Date | When the domain was first registered |
| Expiry Date | When it expires — after this it enters a grace period before being released |
| Updated Date | Last update to the WHOIS record |
| Name Servers | The DNS servers serving the domain |
| Status | Domain status (clientTransferProhibited, redemptionPeriod, etc.) |
Domain Status Codes — What They Mean
The status code in WHOIS says a lot about the domain's condition:
- clientTransferProhibited — Domain cannot be transferred to another registrar (common, protective)
- clientDeleteProhibited — Cannot be deleted — usually for premium/critical domains
- clientUpdateProhibited — WHOIS details cannot change without removing the lock first
- pendingTransfer — Transfer in progress (takes 5–7 days)
- redemptionPeriod — Domain has expired but is in a grace period (30–90 days, renewal with extra cost)
- pendingDelete — Being prepared for release — cannot be renewed
redemptionPeriod, renew it immediately — after pendingDelete there is no recovery.
How to Use WHOIS Results
Check if a domain is available
If no WHOIS record is returned, the domain is likely available. Always confirm availability through a registrar as well.
Check when a competitor's domain expires
Many people monitor domains they want to acquire — if they expire and aren't renewed, you can register them.
Find the registrar for a transfer
If you bought a website or business and want to transfer the domain, WHOIS tells you where it is and who to contact.
Verify nameservers
Especially useful when switching DNS providers — confirm the nameservers have been updated correctly.
Check WHOIS data for any domain:

Since 2018 (GDPR), personal details in WHOIS are automatically hidden for domains owned by Europeans. Also, many registrars offer a "WHOIS Privacy" service that replaces your details with a proxy email/address.
