DHCP
DHCP is a network protocol designed to allow devices connected to a network to communicate
with each other using an IP address. The connection works in a client-server model, in which
DHCP clients request an IP address from a DHCP server. The router comes with a built-in DHCP
(Dynamic Host Control Protocol) server which assigns an IP address to a computer (DHCP client)
on the LAN automatically. The router can also serve as a relay agent which will forward DHCP
requests from DHCP clients to a DHCP server on the Internet.
The IP allocation provides one-to-one mapping of MAC address to IP address. When a computer
with a MAC address requesting an IP address from the router, it will be assigned with the IP
address according to the mapping. You can choose one from the client list and add it to the
mapping list.
