modem router will work as a DHCP Server, it becomes the default gateway for DHCP client
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 clients on the network.
Figure 4-16
Starting IP Address:

Address is
192.168.1.100

but smaller than 192.168.1.254.

The max user pool size.
Lease Time:
The length of time for the IP lease. After the dynamic IP address has
