To access a machine on your local network, it is generally easier to do it through a name than an IP address (just because it is easier to remember). For that it is enough to tell your name server which name match which IP.
All you have to do is specify for each machine its static IP (by opposition to dynamic DHCP IP), and the associated name, as shown in Figure 1.5.
Launch the wizard as many times as needed for each machine you want to associate a formal name to.
