Introduction to DHCP Server

Application Environment

The DHCP server is well suited to the network where:
It is hard to implement manual configuration and centralized management.
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.
A few hosts need fixed IP addresses.

DHCP Address Pool

Address pool types
DHCP address pools can be classified into two types:
Common address pool: Supports both static binding and dynamic allocation.
Extended address pool: Supports dynamic allocation only.
