1.1 Introduction to DHCP
With networks getting larger in size and more complicated in structure, lack of
available IP addresses becomes the common situation the network administrators
have to face, and network configuration becomes a tough task for the network
administrators. With the emerging of wireless networks and the using of laptops, the
position change of hosts and frequent change of IP addresses also require new
technology. Dynamic host configuration protocol (DHCP) is developed in this
background.
DHCP adopts a client/server model, where DHCP clients send requests to DHCP
servers for configuration parameters; and the DHCP servers return the corresponding
configuration information such as IP addresses to configure IP addresses
dynamically.
A typical DHCP application includes one DHCP server and multiple clients (such as
PCs and laptops), as shown in
