Thanks everyone.

How about this then from page 4, about class A networks:

"Each Class A network address has an 8-bit network prefix, with the
highest order bit set to 0 (zero) and a 7-bit network number, followed
by a 24-bit host number...

A maximum of 126 (27 -2) /8 networks can be defined. The calculation
subtracts two because the /8 network 0.0.0.0 is reserved for use as the
default route and the /8 network 127.0.0.0"

12^6? Is 27 - 2 supposed to be 128 - 2?
