Introduction to DHCP Server
Application Environment
The DHCP server is well suited to the network where:
z It is hard to implement manual configuration and centralized management.
z The hosts are more than the assignable IP addresses and it is impossible to assign a fixed IP
address to each host. For example, an ISP limits the number of hosts accessing the Internet at a
time, so lots of hosts need to acquire IP addresses dynamically.
z A few hosts need fixed IP addresses.
