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.

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.
