To hide your domain name information, you can use domain privacy, also known as WHOIS protection. This service is typically offered by domain registrars and involves replacing your personal contact information, such as name, address, and phone number, with generic contact details provided by the registrar. This way, your personal information is shielded from public access and potential misuse by spammers, marketers, and identity thieves. When someone performs a WHOIS lookup on your domain name, they will see the registrar’s contact details instead of yours. Domain privacy typically comes with an annual fee, which varies depending on the registrar and the TLD (Top-Level Domain) you have registered.
