Usage Guidelines
This command first appeared in Cisco IOS Release 12.0(1)T.
This command is valid for DHCP subnetwork address pools only. If the mask or prefix length is not
specified, the class A, B, or C natural mask is used. The DHCP server assumes that all host addresses
are available. The system administrator can exclude subsets of the address space by using the ip
dhcp excluded-address command.
You can not configure manual bindings within the same pool that is configured with the network
command.
Examples
The following example configures 172.16.0.0/16 as the DHCP pool’s subnetwork number and mask:
network 172.16.0.0 /16

mask (Optional) The bit combination that renders which portion of the
address of the DHCP address pool refers to the network or subnet and
which part refers to the host.
/ prefix-length (Optional) Specifies the number of bits that comprise the address
prefix. The prefix is an alternative way of specifying the network mask
of the client. The prefix length must be preceded by a forward slash (/).
