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

dhcpd address 192.168.16.1-192.168.16.11

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

Cheers

It is currently on the 192.168.1.1-192.168.1.254 range, when I use the command dhcpd address 192.168.0.1-192.168.0.1-
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 172.17.1.0 with netmask 255.255.255.0, then 172.17.1.0 (network IP) and 172.17.1.255 (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 10.0.1.101-10.0.1.110 inside
