🔍 WHOIS Domain Lookup

🔍 What is WHOIS?

WHOIS is a query protocol widely used for querying databases that store registered domain information. It provides details about domain ownership, registration dates, expiration dates, and name servers.

🌐 RDAP vs Traditional WHOIS

This tool uses RDAP (Registration Data Access Protocol) as the primary method, with WHOIS API fallback. RDAP provides structured, standardized responses and better support for internationalized domains compared to traditional WHOIS text-based queries.

✨ Features

• RDAP-first approach for accurate, structured data
• Fallback to WHOIS APIs for broader domain coverage
• Domain registration and expiration date information
• Name server and status information
• Contact information (when available and not redacted)
• Multiple data sources for comprehensive coverage
• Privacy-focused: queries are not logged
• Fast response times with proper error handling

🔒 Privacy Note

Many domains now have redacted contact information due to GDPR and other privacy regulations. This tool respects privacy policies and displays available public information only.
