Domain Name Server (DNS) Configurator Introduction An IP network works with numbers. Each machine has a unique four part number, but it is easier for humans to work with names than with num- bers. Further, it is easier to work with names if they are organized in groups, and those groups can potentially be subdivided into sub- groups. A group is called a _d_o_m_a_i_n. A machine acting as a translator from names to IP numbers is called a DNS. It is a server which either knows how to translate a machine name to its IP number or knows how to ask other DNSs if it can't do the translation itself. 11.. ttaasskkss DDoommaaiinnss +o Defining the _d_o_m_a_i_n_s managed by this _D_N_S.
