Thank you, kind sir. This is exactly what I was looking for:
[may '96 figures]
Grand Total (Allocated and Assigned Combined)
Class A - 127128 <--
Bit pattern 0xxxxxxx Class A (0-127)
Bit pattern 10xxxxxx Class B (128-191)
Bit pattern 110xxxxx Class C (192-223)
Bit pattern 1110xxxx Class D (224-239)
I give up. Where did I go wrong that I think net 128.x.y.z is in the
old style class B range?
