Free Whois Lookup Tool
Look up the registration details of any domain name. This tool queries the authoritative WHOIS server for the domain’s TLD and returns registrar information, registration dates, expiration status, nameservers, and domain status codes – all in a clean, readable format.
How to Use This Tool
- Enter a domain name – type or paste a domain like
example.com. The tool accepts bare domains, full URLs (protocol and path are stripped automatically), and supports 40+ TLDs including .com, .net, .org, .io, .co.uk, .de, .fr, .app, and more. - Click “Lookup” to query the appropriate WHOIS server. Each TLD has its own authoritative WHOIS server (for example, .com domains query
whois.verisign-grs.com, while .org domains querywhois.pir.org). - Review the parsed results. The tool extracts key fields from the raw WHOIS response and displays them in a structured format. You can also view the full raw WHOIS text if you need the complete, unprocessed output.
Understanding Your Results
WHOIS results contain several important pieces of information:
| Field | What It Tells You |
|---|---|
| Registrar | The company through which the domain was registered (e.g., GoDaddy, Namecheap, Cloudflare). This is where the domain owner manages their registration. |
| Creation Date | When the domain was first registered. Older domains often carry more trust in search engine algorithms. |
| Expiration Date | When the registration expires. If the owner doesn’t renew before this date, the domain eventually becomes available for anyone to register. |
| Updated Date | The last time the WHOIS record was modified – usually after a renewal, registrar transfer, or nameserver change. |
| Nameservers | The DNS servers authoritative for the domain. These tell you where the domain’s DNS is hosted (e.g., Cloudflare, AWS Route 53, the registrar’s own servers). |
| Status Codes | EPP status codes that describe the domain’s current state. The tool provides plain-language explanations for each code. |
Common status codes explained:
- clientTransferProhibited – the registrar has locked the domain to prevent unauthorized transfers. This is standard security practice.
- clientDeleteProhibited – the domain is protected against accidental deletion.
- serverHold – the registry has suspended the domain, usually due to a legal dispute or non-payment. The domain won’t resolve.
- redemptionPeriod – the domain has expired and is in a grace period where only the original registrant can renew it (usually at a premium fee).
- pendingDelete – the domain is about to be released back to the public pool for registration.
Why This Matters
WHOIS data helps you answer practical questions about any domain on the internet. Investigating a suspicious email? Check when the sender’s domain was registered – domains created days or weeks ago are a strong phishing signal. Interested in buying a domain? WHOIS tells you the registrar and sometimes the owner, giving you a path to make contact.
For website owners, regular WHOIS checks on your own domains help you catch expiration dates before they sneak up on you. A domain that accidentally expires can be snatched by domain squatters within hours, and getting it back is expensive and uncertain. Set calendar reminders based on the expiration dates you see here.
Security researchers and IT teams use WHOIS to trace the infrastructure behind phishing campaigns, identify shared hosting patterns, and verify that their organization’s domains have proper transfer locks in place.
Frequently Asked Questions
Why does WHOIS show “REDACTED FOR PRIVACY” instead of the owner’s name?
Since the EU’s General Data Protection Regulation (GDPR) took effect in May 2018, most registrars redact personal information from public WHOIS results by default. You’ll typically see the registrar’s privacy service or “REDACTED FOR PRIVACY” in the registrant fields. This applies to all domains, not just those registered in Europe. To contact the domain owner, you can usually reach them through the registrar’s contact form or the email address listed in the WHOIS record (often a forwarding address through a privacy service).
Which TLDs does this tool support?
The tool supports 40+ top-level domains including all major gTLDs (.com, .net, .org, .info, .biz, .xyz), popular ccTLDs (.uk, .de, .fr, .nl, .eu, .ca, .au, .jp, .br, .in, .ru, .kr, .se, .no, .fi, .dk), and newer extensions (.io, .co, .app, .dev, .tech, .site, .online). Each TLD has a specific WHOIS server mapped in the tool. If a TLD isn’t in the mapping, the lookup may not return results.
How current is the WHOIS data?
WHOIS queries go directly to the authoritative server for each TLD, so the data is as current as the registry’s records. Results are cached on our server for one hour to reduce load on WHOIS servers and stay within query limits. If you’ve just made DNS or registrar changes, wait an hour and try again to see the updated record.
How this tool works
This tool runs entirely in your browser and our server. We detect your IP address server-side, then perform DNS and WebRTC checks client-side. No account is needed and no personal data is stored beyond anonymous aggregate statistics.
Results are based on real-time checks against your current connection. For the most accurate results, ensure your VPN is fully connected before running the test.
