The term is derived from the English word ‘domain’ (i.e., possession, ownership). This represents the right to possess a certain name for a certain period of time. Each name corresponds to the numeric IP address of a particular computer on the Internet.
Domain names are unique and may not be repeated. After registration of a domain name and its assignment to a certain website and/or email address, the user makes this website and email accessible and visible by any other computer as part of the World Wide Web.
