Comprehensive WHOIS & Domain FAQ

Understanding registry directories, data accuracy, and user privacy compliance

How does a WHOIS lookup work?

When you search a domain using our tool, a request is dispatched to the Internet Assigned Numbers Authority (IANA) database to locate the authoritative registry server (e.g. Verisign for .com). The tool then queries the registry using modern Registration Data Access Protocol (RDAP) servers or standard port 43 TCP commands to fetch registration details.

What is the difference between WHOIS and RDAP?

Traditional WHOIS operates on raw TCP connections over Port 43, returning plain text results that vary by registry. RDAP (Registration Data Access Protocol) is the modern successor. It queries registries over HTTP, returning structured, JSON-formatted data. This ensures standard styling, secure access controls, and more reliable uptime.

Are WHOIS search queries kept private?

Yes. Under our data privacy guidelines, we operate a strict zero-logs policy. Your searches are processed in real-time, and we do not store log data connecting your IP address to searched domain names. This keeps your domain research and brand strategy entirely confidential.
