DHCP server configuration examples
DHCP networking includes the following types:
• The DHCP server and clients reside on the same subnet and exchange messages directly.
• The DHCP server and clients are not on the same subnet and they communicate with each other
through a DHCP relay agent.
The DHCP server configuration for the two types is identical.
