What Is WHOIS?
WHOIS is the familiar name for domain-registration queries. Modern services increasingly obtain structured registration data through RDAP while users continue searching for WHOIS, domain-owner lookup, domain-age checker, and expiration checker.
Information a Lookup May Show
Registrar
The company through which the domain is registered.
Creation Date
The date the current registration record was created.
Expiration Date
The scheduled end of the current registration period.
Updated Date
The date registration data was last modified.
Nameservers
The DNS servers delegated for the domain.
Status Codes
Transfer locks, update locks, holds, pending transfer, or pending deletion.
Registrant Data
May be public, redacted, or replaced by a privacy service.
WHOIS vs RDAP
Traditional WHOIS returns loosely formatted text. RDAP provides structured responses and improved handling of internationalization and access control. A modern WHOIS page may use RDAP behind the scenes.
How to Run a Domain Lookup
- Enter only the domain name.
- Do not include a page path.
- Run the lookup.
- Review the registrar, dates, nameservers, and status.
- Confirm critical data directly with the registrar if you own the domain.
Correct Input
example.comA full URL such as https://www.example.com/page is unnecessary.
How to Find Who Owns a Domain
Review the registrant section, but understand that privacy rules often hide personal data. A registrar, hosting company, DNS provider, or privacy service shown in the result is not automatically the actual website owner.
How to Check Domain Age
The creation date is commonly used as an age indicator, but the current website or owner may be much newer. The domain may also have expired, changed ownership, or been repurposed.
How to Check Expiration
Review the registry-expiry or expiration field, then verify the renewal date in the registrar account.
- Enable automatic renewal
- Keep the payment method current
- Maintain access to the registrant email
- Protect the account with MFA
- Do not assume the domain becomes available immediately after expiry

Frequently Asked Questions
Can WHOIS show the owner's name?
Sometimes, but personal information is frequently redacted or protected by a privacy service.
Can WHOIS identify the hosting provider?
Not reliably. It normally identifies the registrar. Use DNS and IP research for hosting information.
Does the expiration date mean immediate availability?
No. Renewal, grace, redemption, and deletion periods can apply.
Can WHOIS prove who operates a website?
No. Registration information may be private, outdated, or different from the website operator.
