On the Internet everyone wants to communicate. That globally common communication language is IP (Internet Protocol). Every Internet server must have an IP address in order to be accessed via the Internet. Every computer running a web browser must have or be translated to an IP address to access the Internet. The commonly used version of IP addresses is called IP Version 4 (IPv4). It was originally designed in 1980 as a means to interconnect mainframe computers. Of course this was well before the invention of personal computers and three decades before the privatization and commercialization of the Internet.
