5.5 DHCP Server
Dynamic Host Configuration Protocol (DHCP) is a protocol for assigning dynamic IP
addresses to devices on a network. With dynamic addressing, a device may have a
different IP address every time it connects to the network. In some systems, the IP
address may change while connected. DHCP supports a combination of static and
dynamic IP addresses. Dynamic addressing simplifies network administration because
the software keeps track of IP addresses rather than an administrator managing this task.
This means that a new computer can be added to a network without the hassle of
manually assigning it a unique IP address.

192.168.1.200 , 192.168.1.100 will be the Low IP address.
