4.3 Changing DHCP server configuration
DHCP is used to acquire IP addresses and options (such as the subnet
mask, DNS, gateway, etc.) automatically. On the practical level, acquiring
these initialization parameters with DHCP translates into avoiding the
more involved Router/PC process (reconfiguration of Router and/or PC
addresses in the same network.
