Not quite. It's not an xor, its an or operation.

Digging a bit further discovered that its all an XOR operation
so if you want to allow networks 200.0.0.2, 200.0.0.4 and 200.0.0.6
then convert the last octets 2,4 and 6 in binary and perform XOR.
2: 00000010
4: 00000100
6: 00000110
------------------ XOR
00000110 =6
so the mask will be 0.0.0.6
