same as subnets but kinda in reverse.

acl mask +1 gives clues to network

15 + 1 = 16

subnet increment would be 16

your network address range would be 192.168.54.0 - 192.168.54.15


your acl would permit 192.168.54.1 - 192.168.54.15

it's gets a little more complex for networks like 192.168.54.48
255.255.255.240

Access-list 1 permit 192.168.54.48 0.0.0.15

15+1 = 16
subnet increment is 16

network is 192.168.54.48 - 192.168.54.63

this acl would permit 192.168.54.49 - 192.168.65.63
