I believe the calculation below yields 150 not 151. It is an exclusive OR
calculation. All 1's should equal a 0.

OK, so:
1 = 0 0 0 0 0 0 0 1
3 = 0 0 0 0 0 0 1 1
5 = 0 0 0 0 0 1 0 1
147 = 1 0 0 1 0 0 1 1
----------------------
X 0 0 X 0 X X 1 = 10010111 = 151
and the result is 201.201.1.0 0.0.151.0
