About Whois Lookup
Look up domain registration details and availability instantly. Our WHOIS tool queries public registries to find out who owns a domain, when it was registered, and when it's set to expire, helping you manage your web assets or research potential acquisitions.
How to Use
- Enter the domain name (e.g., example.com) into the lookup field.
- Click 'Lookup' to query global domain registration databases.
- Review the registration date, expiration date, and nameserver info.
- If the domain is available, you'll see a 'Domain not found' message, indicating it can likely be registered.
Common Use Cases
- Checking the expiration date of your own domains to prevent accidental loss.
- Researching the registration history and ownership of a website for business intelligence.
- Verifying nameserver configurations to troubleshoot website hosting issues.
Technical Details
Queries the RDAP (Registration Data Access Protocol) standard, the modern, structured successor to the traditional WHOIS protocol, providing faster and more reliable results.
Frequently Asked Questions
- Is my personal data visible?
- Due to GDPR and privacy services, most modern WHOIS records redact personal names, emails, and phone numbers by default.
- Can it check any domain extension?
- We support the vast majority of popular TLDs (like .com, .net, .org) and many country-code extensions through the RDAP network.
