Specifying a primary subnet and multiple secondary subnets for a DHCP address pool
In scenarios where the DHCP server and the DHCP clients reside on the same subnet, the DHCP server
needs to assign addresses in different address ranges to the DHCP clients. To meet this need, you can
specify a primary subnet and multiple secondary subnets in an address pool. Upon receiving a client
