Allow 172.17.2.64 0.0.0.63 to telnet, or deny 172.17.2.96 0.0.0.63... You are simply shifting 1 more bit to the right in the netmask... Whenever we are dealing with Half of a subnet range, we can simply shift 1 bit in the subnet mask. Your access-list is not aware of what the real subnet is. I

Re: A different Wildcard Mask [1:2082]

Try this -> Look at the bits in the last octet 96 = 0110 127 = 0111 The common bits are the first three, so you want to mask it like this -> 0001 or, 31 65 = 0101 95 = 0101 The common bits are again the first bits, so again the mask is -> 0001 or 31 So, your list
