WHOIS stands simply for “who is” and is a database that contains a list of all domain names and the information about the owners of those names. There is one WHOIS database for each domain extension. Usually they are publicly accessible, which means that anybody can lookup who the owner of a domain name is.
In order to hide ones personal information, domain owners can make use of a Domain Privacy or WHOIS Privacy service which allows them to hide their personal information. Read more about the Domain Privacy service on our website.
