mask-length: Length of the network mask of an IP address pool. It is an integer in 
the range of 0 to 32.

Use the network command to configure an address range for dynamic IP address 
assignment.

Use the undo network command to remove the address range configured for 
dynamic IP address assignment.

By default, no IP address range is configured for dynamic IP address assignment.

Each DHCP address pool can be configured with only one address range. If you 
execute the network command multiple times, then only the last configured 
address range works.

Related command: dhcp server ip-pool, dhcp server forbidden-ip.

# Configure 192.168.8.0/24 as the address range for the global DHCP address 
pool 0.
