History of WHOIS
In 1982, when the Internet Engineering Task Force (IETF) started a protocol used for creating directory service for users of ARPANET (which became the Internet). The directory simply listed the contact informations that was requested by anyone over the network. The WHOIS protocol eventually inherited by ICANN in 1998.
What is WHOIS?
WHOIS is a TCP-based transaction-oriented query/response protocol that is widely used to provide information services to the INTERNET users. Basically, it tells you “who is” responsible for a domain name or an IP Address.
It is used to provide informations about registered domain names, their registrant’s name, address, email, phone number, administrative and technical contacts, expiration dates, when and where it is registered and the name servers assigned to the domain. Also, referred to as WHOIS data. These data is managed by independent entities known as “registrars” and “registries”. Registrars are the service providers which was used to get the domain name registered and Registries are the organization that manages the registration of the domain names within the domains for which it is responsible, controls the policies of domain name allocation, and technically operates its domain.
You can check the WHOIS information for a domain by using the WHOIS from Domain Tools. See link below.

Private Domain Name Registration
It is an option that registrars provide for the registrants. They will register the domain name that you will be using but they will indicate from the WHOIS informations that they are the owner of the domain name. This option are mostly available on all providers. This is to protect your personal information like email address and telephone number from spammers.
