Instant Whois queries with minimal delay.
What is 'Whois'?
When a domain is registered, the registrar collects contact and technical details and publishes them in the Whois directory — a public record of domain registrations.
Use our Whois tool to quickly check whether a domain is already taken; if it is free, you can register it, otherwise you can contact the owner via the published details or explore alternatives.

Frequently Asked Questions
How can I discover who owns a domain?
Run a Whois lookup on the domain — the results typically list the registrar and the contact records associated with the registration. If privacy protection is enabled, you may need to use the site's contact form or contact the registrar to reach the owner.
What information does the Whois database hold?
Whois entries commonly include the registrar, registration and expiry dates, nameservers, and contact records (registrant, administrative and technical). Exact fields depend on the registry and TLD policies.
Why are some Whois entries redacted or incomplete?
Privacy services and local data-protection laws can mask personal contact details. Registries or registrars may hide certain fields to comply with privacy regulations, so the visible output can vary.
What is the difference between thin and thick Whois?
A thin model returns minimal data (usually registrar and nameservers) and points you to the registrar for full details. A thick model stores full registration and contact details at the registry level, so a single query returns the complete record.
How accurate is Whois data?
Registrars and registries are required to collect accurate contact information, but records can become out of date. If you see incorrect data, contact the domain's registrar to request an update.
Can I change the Whois information for my domain?
Yes — changes are made through your domain registrar. Log in to your registrar account or contact their support to update contact details; updates usually propagate to the Whois directory within a day or so.
How do I run a Whois search?
Enter the domain or IP into our search box and submit. Our tool queries the appropriate WHOIS servers and displays the available registration data.
What is a Whois IP lookup?
An IP whois lookup shows the organization or allocation details for an IP address, similar to domain whois but focused on IP assignments and the responsible network operator.
How can I protect my personal details in Whois?
Use a privacy or proxy service offered by many registrars; these services replace your personal contact details with forwarding contacts. Check with your registrar for available privacy options and legal implications.
Why doesn't the Whois record match my current details?
If your information has changed, update it at your registrar. Changes may take time to appear in public Whois outputs; if a discrepancy persists, contact registrar support for assistance.
Can I register a domain directly from a Whois lookup?
Whois tells you whether a domain is registered. If it's available, you can register it through a registrar or our domain search flow. If it's taken, Whois provides details you can use to contact the owner or explore alternatives.
How do I find when a domain expires?
The registration expiry date is usually shown in the Whois record. Look for the “Expiry” or “Registry Expiry” field in the lookup results.
How do I locate DNS records or the IP location for a domain?
Use DNS lookup or IP location tools to reveal DNS entries and estimate the server's geographical allocation; Whois focuses on registration metadata rather than live DNS answers.
How can I search many domains at once?
Use bulk search features if available (our app supports batch checks) or script repeated lookups against our API, respecting rate limits and terms of use.
