DHCP overview

The Dynamic Host Configuration Protocol (DHCP) provides a framework to assign configuration
information to network devices.
Figure 10 shows a typical DHCP application scenario where the DHCP clients and the DHCP server
reside on the same subnet. The DHCP clients can also obtain configuration parameters from a DHCP
server on another subnet through a DHCP relay agent. For more information about the DHCP relay agent,

Allocation mechanisms

DHCP supports the following allocation mechanisms:
Static allocation—The network administrator assigns an IP address to a client, such as a WWW

server, and DHCP conveys the assigned address to the client.
• Automatic allocation—DHCP assigns a permanent IP address to a client.
Dynamic allocation—DHCP assigns an IP address to a client for a limited period of time, which is
•
called a lease. Most DHCP clients obtain their addresses in this way.
