LAN Wizard: Enable DHCP Server
This screen lets you enable a DHCP server on your router. A DHCP server
automatically assigns reusable IP addresses to the devices on the LAN. When a
device becomes active on the network, the DHCP server grants it an IP address.
When the device leaves the network, the IP address is returned to the pool for use
by another device.
Field Reference

network administrator should determine the IP addresses of LAN
interfaces. For more information, see IP Addresses and Subnet Masks.

The subnet mask enables the router to determine how much o f the IP
address is used to define the network and host portions of the address.
Alternatively, select the number of network bits. This value is used to
calculate the subnet mask. Your network administrator can tell you the
number of network bits to enter.
