Domain privacy, also known as WHOIS privacy, is a service offered by domain registrars that hides the personal contact information of the domain owner from being publicly displayed in the WHOIS database. The WHOIS database is a public directory of registered domain names that includes the name, address, phone number, and email address of the person or organization that registered the domain. When you register a domain name, your personal contact information becomes publicly available in the WHOIS database, which can be accessed by anyone. This means that your name, address, phone number, and email address can be easily found by spammers, marketers, and other individuals or organizations who may use this information for unsolicited marketing or even identity theft. Domain privacy services allow you to keep your personal contact information private by replacing it with the contact information of a third-party service provider. This means that when someone performs a WHOIS lookup on your domain, they will see the contact information of the third-party service provider instead of your personal information. By using domain privacy, you can help protect your personal information from being publicly available in the WHOIS database and reduce the amount of spam and unwanted marketing you receive. However, it's important to note that domain privacy services may come at an additional cost and may not be available for all domain extensions.
