ICANN, the international governing body for domain names, requires every domain registrar to maintain a publicly viewable "WHOIS" database that displays personal contact information (including home addresses and phone numbers) for every registered domain. Domain privacy protects your personal information from being captured via this database.
Because of ICANN's WHOIS policy, the personal information you list when registering your domain is available to anyone with internet access. WHOIS privacy circumvents this privacy issue by displaying our company information rather than your own personal data. Your personal information stays private while you maintain complete ownership and control of your domain.
WHOIS is not an acronym but a phrase that refers to a series of information that identifies, "who is" the owner of a domain name or IP address. When individuals, governments, and businesses register a domain name with ICANN (The Internet Corporation for Assigned Names and Numbers), they must provide the domain name as well as contact information. Such contact information includes the registrant's name, address, phone number, email, technical contacts, and administrative contacts.
By law, some of the WHOIS information must be available for public access. Accordingly, ICANN created a directory to ascertain the identity of domain name registrants.
