What is Whois and Whois++

WHOIS (pronounced as the phrase "who is") is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format

The WHOIS++ protocol is a distributed directory system, originally designed to provide a "white pages" search mechanism to find humans, but which could actually be used for arbitrary information retrieval tasks

Whois Guard

Whois Guard is a protection mechanism used by domain registrars to protect contact details of registrants from being accessed by the public. Whois replaces the registrants details such as email address, phone number and physical address with designated contact details. Namecheap currently provides free whois guard for life though while ago they used to charge some few cents. I guess it's because in the long run they also benefit as dealers when selling domains.

Registrar vs Registrant

Registrar is an organization that manages domain name service(DNS). It can be domain seller or reseller company. A domain name registrar must be accredited by a generic top-level domain (gTLD) registry (.com, .net, .info etc) or a country code top-level domain (ccTLD) registry (.me, .us, .uk, .de etc).

The domain name registrant is the organization or individual registering the domain name. A registrant is a successful applicant of a domain name granted by the registrar. Anonymous registrant is the one using whois guard protection to mask his/her identity.

Whois Servers

A Whois server is an entity set-up by an ICANN accredited registrar to acquire up-to-date information about domains that are registered within it. Every ICANN registrar is mandated to maintain a Whois server according to the ICANN agreement.
