WHOIS is not an acronym although it appears as one, it's pronounced as the phrase 'who is' and is a protocol used to query databases. WHOIS stores data of every website that’s on the internet. WHOIS stores data of the domain name, its registrant, and registrar. The registrant is the owner of the domain, and the registrar is the party responsible for registering the domain. The WHOIS checker tool displays the complete information about the domain.

WHOIS history can be traced back to the early days of the internet. In 1982 Internet Engineering Task Force published a protocol for a directory service for ARPANET users. With the advent of Internet, WHOIS began to serve the needs of different users.

Today, there are millions of individuals, firms, business organizations; educational institutions and governments register domains. They start by seeing if the domain name that they want to register is available. They do this by using domain name sellers sites like Godaddy, Namecheap, etc. These sites use WHOIS to check if a domain name is available. If available they sell it to the customer.

WHOIS does not maintain a single database of all the registered domains. It is managed by a network of independent entities known as registries and registrars. The entities are responsible for maintaining accurate records of the domain names contact information. It includes data of the domain name owner and contact details, plus that of where the domain is being hosted from.

Individuals, businesses, educational institutions utilize hosting services which are provided by firms that are in this business. The hosting service provider has the infrastructure and expertise to provide internet services.

Any business entity that wants to become a WHOIS registrar must earn ICANN certification. The entity must also have the equipment, utilities, and workforce to run and maintain this service. WHOIS registries must allow anyone to search and view the domain name registered holder's name and contact data.

The Whois checker tool is provided by some SEO tools providers on the internet. The searchenginereports.net provides the WHOIS checker tool. When you use this tool, you can get information on three domains. The report generated shows the domain name, if it's registered, the name servers, registrar and the expiry date of the domain.

Security agencies use this information if they want to shutdown a domain and want to know who owns it. Government agencies want to know which sites are putting out malicious news or are criticizing the government. The individual business owner may want to see who their rivals on the internet are. This information is easy to come by with a WHOIS checker.

WHOIS data is stored and looked up using a thick or thin lookup. Thick data is stored in a WHOIS server of a particular data set. For example all the .edu WHOIS servers will have all the data of domains that have .edu in their name.

A thin WHOIS server only contains the information that services a particular area. This is in turn connected to a thick server that has the complete information of that data set.
