I guess you are looking for the command?
Example for changing your DHCP POOL

dhcpd address

Keep in mind depending on the version of the IOS you are limited in the number DHCP Host addresses.
5.2 10
5.3 32
6.0 32

It is currently on the range, when I use the command dhcpd address
It says the interface is not on the same subnet as DCHP pool

You cannot configure a DHCP server for 256 clients, using a Class C netmask. For example, if a company has a Class C network address of with netmask, then (network IP) and (broadcast) cannot be in the DHCP address pool range. Further, one address is used up for the PIX Firewall interface. Thus, if a user uses a Class C netmask, they can only have up to 253 DHCP Clients.

Specify a DHCP address pool using the dhcpd address command. The PIX Firewall will assign to a client one of the addresses from this pool to use for a given length of time. The default is the inside interface.

For example:

dhcpd address inside
