When registering a domain, you are required by *ICANN to provide Z.com with up-to-date personal information, such as name and contact details, which must be displayed publicly.
* ICANN (Internet Corporation for Assigned Names and Numbers) is a private, non-profit organization and governing body that aims to coordinate various internet resources, such as domain names worldwide.
The ICANN Registrar Accreditation Agreement (RAA) stipulates that all registrars disclose their domain holder’s personal information (Whois data) without monopoly. Therefore, the Whois information for your domain will be disclosed when registering with any ICANN-approved registrar, including Z.com.
As domain registrations have increased in recent years, there has been an increasing tendency to consider domains as “intellectual property”. As a result, Whois information is commonly displayed to resolve disputes between domain holders and trademark holders smoothly.
