Hi,Your prefix is 200.0.0.2. Convering last octet to binary, which is where the action is: 200.0.0. 0000 0010. Mask is 0.0.0.14, again in binary: 0.0.0. 0000 1110 Prefix and mask, remembering that 0 in mask is match and 1 in mask is "don't care": 200.0.0. 0000 0010 0.0.0. 0000 XXX0 So, the last bit of your mask is "must match" and the last bit of your prefix is a zero. There, matched prefixes must be even, and therefore cannot be odd. Hence .3, .5 etc will not match.
