Domain privacy protection is a service that hides your personal information from the public. This information includes your name, address, phone number, and email address. When you register a domain name, your personal information is automatically added to the WHOIS database. This database is public, and anyone can view it. Domain privacy protection prevents your information from being displayed in the WHOIS database. There are many reasons why you would want to keep your information private. For example, if you own a business, you may not want competitors to be able to find out your contact information. Or, if you are concerned about spam or identity theft, you may not want your email address or phone number to be publicly available. Domain privacy protection is not required, but having it is a good idea if you want to keep your information private.
