6.3.2 Checking the Allocatable IP Addresses

To check the number of IP addresses that can be assigned to clients, execute the show ip dhcp server statistics command and check the address pools field in the displayed list. Make sure that the number displayed here is greater than the number of IP addresses you want to assign to clients.
