DHCP is a network protocol used to configure devices that are connected to a
network so they can communicate on that network using the Internet Protocol (IP) .
You could set up the DHCP server or DHCP relay, and view the DHCP status .

(This function is similar to the DHCP service in NT servers . ) It benefits users by
freeing them from the inconvenience of recording and configuring IP addresses
for each PC . When a computer is turned on, it will acquire an IP address from the
device automatically .
