ONFIGURATION
As the network scale expands and the network complexity increases, the network
configurations become more and more complex accordingly. It is usually the case that
the computer locations change (such as the portable computers or wireless networks)
or the number of the computers exceeds that of the available IP addresses. The
dynamic host configuration protocol (DHCP) is developed to meet these
requirements. It adopts the client/server model. The DHCP client requests
configuration information from the DHCP server dynamically, and the DHCP server
returns corresponding configuration information based on policies.
A typical DHCP implementation usually involves a DHCP server and multiple clients
(such as PCs and portable computers), as shown in Figure 21.

The interactions between a DHCP client and a DHCP server are shown in Figure 22.
