Domain Name Server(DNS) Configurator Introduction An IP network works with numbers. Each machine has a unique 4 parts number. It is easier to work with names than with numbers. Further, it is easier to work with name if they are organized in groups, and potentially those groups subdivided in 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 it itself. 11.. ttaasskkss DDoommaaiinnss +o Defining the _d_o_m_a_i_n_s managed by this _D_N_S.
