WHOIS Lookup:
Enter a domain name or IP address and click Search to see available information.
Limitations: Only basic data is displayed without an API key. For IP addresses, available information includes IP, hostname, ISP, city, region, country, latitude, and longitude. For domains, only publicly available DNS records (A, NS, MX, etc.) are shown. Full WHOIS records, ASN, and registrar details require an API key or a server-side proxy.
