Private registration typically refers to the process of registering a domain name without publicly disclosing the personal information of the domain owner. When you register a domain name, you're required to provide contact information such as name, address, email, and phone number. This information is then added to the WHOIS database, which is publicly accessible.

With private registration, also known as WHOIS privacy or domain privacy protection, the domain registrar replaces your personal information with the registrar's information in the WHOIS database. This helps to keep your contact details private and reduces the risk of spam, identity theft, and other forms of online abuse.
