Domain RDAP Intelligence
Look up any supported domain to see its registration status, key dates, registrar, and owner details — then explore how entities are connected across domains through shared addresses.
🌐
Domain Lookup
Enter any supported domain. If we have it cached we return it instantly including registration, expiry and last changed dates. If not, we query the registry RDAP API live and store the result.
🏢
Entity Profiles
Click any registrant, registrar, or contact to see their full profile — including every domain they appear on across all supported TLDs.
🔗
Relationship Discovery
Entities that share a registered address are automatically linked, revealing connections between seemingly unrelated domains.
Tips
- • Subdomains are automatically stripped — fit.cvut.cz searches for cvut.cz
- • URLs work too — paste https://www.google.cz/search?q=test and we'll extract google.cz
- • Use the browser back button to navigate back through your search history
- • Unsupported TLDs show a clear message with the list of what is supported
