In order to be well-defined on the Internet every computer which can be reached via Internet is endowed with a numeric address (e.g. the order of numbers 188.8.131.52 for a safog.com web-server). Numeric addresses, also called IP-addresses (with IP being the abbreviation of "Internet Protocol"), are the "house numbers" of computers. Domain names
Humans, however, prefer names, and for this very reason a system has been developed which allows matching computers with logical names. The so-called domain-name-system had been created, a clear and logical global name structure which allocates a hierarchically structured name to every computer connected with the Internet.
Generic domains are used to label computers as regards subject matter. They indicate to which group of Internet users the respective institution or company belongs.
Geographic domain names are used to identify the position of a computer, i.e. the country where it is to be found. They inform about which nationality the respective institution or company offering the service belongs to.
Some of these geographic domain names may also be "abused" in a way to achieve a specific denomination.
