What is WHOIS?

WHOIS is a query and response protocol used for querying databases that store registered domain names, IP addresses, and their owners. It provides information about domain registration, expiration dates, registrar details, and nameservers. This information is essential for network administrators, security researchers, and legal purposes.

How Domain Lookup Works

Domain lookup queries multiple sources: WHOIS servers maintained by domain registries provide registration details, DNS servers return name resolution records, and SSL/TLS connections reveal certificate information. Each Top-Level Domain (TLD) has its own WHOIS server with potentially different data formats.

Frequently Asked Questions

Why is WHOIS information hidden for some domains?

Many registrars offer WHOIS privacy protection services that replace the owner's personal information with the registrar's or a proxy service's details. This protects domain owners from spam and unwanted contact.

What is RDAP?

RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides the same information in a standardized, machine-readable JSON format with better security and access control features.
