Try this ->
Look at the bits in the last octet
96 = 01100000
127 = 01111111
The common bits are the first three, so you want to mask it like this ->
00011111 or, 31
65 = 01000001
95 = 01011111
The common bits are again the first bits, so again the mask is -> 00011111
or 31
So, your list should be be
deny 171.17..2.96 0.0.0.31
permit 172.17.2.64 0.0.0.31
