WHOIS Lookup

Look up WHOIS information for domains and IP addresses. See registrar, registration dates, status, name servers and IP allocation details in a clean, modern interface.

Domain or IP
Paste any domain (with or without https://) or IPv4/IPv6 address.
Detection & mode

AUTO Type will be auto-detected after lookup.

The tool decides whether to run a domain WHOIS or IP WHOIS and queries the relevant registries.
Notes
Some registries limit WHOIS access or hide personal data due to privacy and GDPR rules. In those cases you still get technical information like registrar, dates and name servers.

Why Some Fields Are Hidden or Empty

      
Modern WHOIS output is heavily influenced by privacy rules and GDPR. Many registries hide personal contact data or replace it with a privacy proxy. In those cases, you can still see technical fields like registrar, dates, status and name servers, but contact names or emails may not be shown.


      
Best Practices for Using WHOIS Data

      
    
        
  • Use WHOIS to verify ownership and registration dates before buying or negotiating for a domain.
    • 
        
  • Check expiry dates to plan renewals and avoid accidental loss of important domains.
    • 
        
  • Use IP WHOIS results to identify the network owner when investigating abuse or security incidents.
    • 
        
  • Respect privacy laws and registry terms – do not use WHOIS data for spam or unsolicited marketing.
