DHCP Configuration

This section contains DHCP configuration information.

Overview of DHCP

Dynamic Host Configuration Protocol (DHCP) offers dynamic IP address assignment.
DHCP works in Client-Server mode. With this protocol, the DHCP Client can
dynamically request configuration information and the DHCP server can configure the
information for the Client.

The DHCP relay serves as conduit between the DHCP Client and the server located on
different subnets. The DHCP packets can be relayed to the destination DHCP server
(or Client) across network segments. The DHCP clients on different networks can use
the same DHCP server. This is economical and convenient for centralized
management.

A typical DHCP application often contains a DHCP server and several clients (desktop
and laptop PCs). See Figure 65
