When you register a domain, ICANN requires your name, address, phone, and email to be listed in the public WHOIS database — visible to anyone. Domain Privacy Protection replaces your personal details with generic proxy information, keeping your real contact details hidden from spammers, scrapers, and unwanted marketers while still meeting legal requirements. We recommend enabling privacy protection for all personal or small-business domains unless you specifically need public WHOIS visibility (e.g., for certain business/legal domain types).
