When you use DHCP Manager to configure the server, the first network is also configured at the same time. The first network is usually the local network on the server system's primary interface. If you want to configure additional networks, use the DHCP Network Wizard in DHCP Manager.
If you use the dhcpconfig -D command to configure the server, you must separately configure all networks that you want to use the DHCP service. See How to Add a DHCP Network (dhcpconfig) for more information.
When you configure a new network, DHCP Manager creates the following components:
A network table in the data store. The new network is shown in the network list within the Addresses tab of DHCP Manager.
A network macro that contains information needed by clients that reside on this network. The network macro's name matches the IP address of the network. The network macro is added to the dhcptab table in the data store.
