The Modem Router will work as a DHCP server, it becomes the default gateway for DHCP clients
connected to it. DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives out IP
addresses when a device is booting up and request an IP address to be logged on to the
network. That device must be set as a DHCP client to obtain the IP address automatically.
By default, the DHCP Server is enabled. The DHCP address pool contains the range of the IP
address that will automatically be assigned to the network clients.
