How to use the WHOIS lookup

  1. Enter the domain

    Type the domain name (without http://) into the WHOIS lookup field.

  2. Run the lookup

    Click 'WHOIS Lookup' to query the WHOIS database for the domain's registration details.

  3. Review registration info

    See the registrar, registration date, expiry date, and nameservers.

  4. Check domain age

    Note the domain's creation date — older domains typically have more established authority.

  5. Note expiry date

    If researching domain acquisition, note the expiry date to monitor when it may become available.

What is a WHOIS lookup?

The WHOIS Lookup tool retrieves registration information for any domain name from the global WHOIS database. It shows the domain's registration date, expiry date, registrar, nameservers, and any available registrant contact details (subject to GDPR privacy masking).

WHOIS data is used to verify domain ownership, check when a domain expires (important for competitive domain acquisition), verify a site's age and history, and research the background of websites for competitive analysis or due diligence.

Why use a WHOIS lookup?

Understanding domain registration details is valuable for competitor research (how long has this domain been active?), security investigations (who owns this suspicious domain?), and purchasing decisions (when does this expired domain become available?). WHOIS data also helps verify the age and trust signals of websites you're planning to build links with.

What is WHOIS?

WHOIS is a query protocol used to look up information about domain name registrations. It provides details about who registered a domain, when it was registered, when it expires, and which registrar manages it.

Why might WHOIS show 'private' or 'redacted' for owner details?

Many registrars offer WHOIS privacy protection that replaces personal contact details with proxy information. GDPR privacy regulations have also led to widespread redaction of European registrant data.

Does domain age affect SEO?

Domain age is a minor SEO factor. Older domains have longer track records and typically more accumulated links and authority. However, new domains with great content can outrank old domains — age alone is not determinative.

How can I check when a domain will expire?

The WHOIS record shows the domain's expiry date. If you're monitoring a competitor's domain or looking to acquire an expiring domain, check the expiry date and set reminders accordingly.

Can I find out who owns any domain?

For many domains, WHOIS shows registrant details. However, privacy protection services and GDPR compliance mean that an increasing number of domains show proxy or redacted registrant information instead of the actual owner's details.
