WHOIS Lookup Tool

Look up domain registration details including owner, registrar, creation date, expiration date, and nameservers.

## What WHOIS Shows You A WHOIS lookup reveals key information about any domain: - **Registrant**: Who owns the domain (may be redacted for privacy) - **도메인 등록기관 (레지스트라)**: Which company manages the registration - **Dates**: Creation, last update, and expiration - **Nameservers**: Where the domain's DNS is hosted - **Status codes**: Lock status and other flags ## WHOIS vs RDAP RDAP is the modern successor to WHOIS, providing structured JSON responses and better access control. This tool tries RDAP first and falls back to WHOIS for older TLDs.
