5.4 Setting Up the DHCP Server

5.4.1 Setting Up the DHCP Server in the Window 2003 Server

Basics Concepts
The Dynamic Host Configuration Protocol (DHCP) is mainly used to allocate dynamic IP
addresses to terminals on the same network. When DHCP is used, a DHCP server needs to be
deployed on the network and IP phones function as DHCP clients.
When a DHCP client sends a request for a dynamic IP address, the DHCP server provides an
available IP address and subnet mask for the DHCP client according to the preserved IP
address set.
The DHCP has two port numbers, that is, port 67 for the DHCP server and port 68 for the
DHCP client. This means that the DHCP client selects only port 68, rather than a temporary
port that is not used.
Here, the two ports are selected because a response from the DHCP server can be broadcast.
The following figure shows the process for an IP phone to obtain the IP address through
DHCP.
