to make available (private) ip addresses accessible to dhcp clients, add a subnet. to add a new subnet, you specify a range of ip addresses to be assigned to clients on the network. for example, you could define the address range from 10.1.1.10 to 10.1.1.19 to give clients a pool of 10 addresses. from policy manager:
1 select network =] dhcp server.
2 click add.
the dhcp subnet properties dialog box appears, as shown in the following figure.

3 in the subnet box, type the subnet’s ip address; for example, 10.1.1.0/ 24.
4 define the address pool by entering values for start and end fields.
5 click ok.
