Not quite sure where you got that prefix list from, but it doesn't look
right.
If you just want to match Class A's with 8 bit masks, Class B's with 16 bit
masks, and class C's with 24 bit masks.
0.0.0.0/1 ge 8 le 8
128.0.0.0/2 ge 16 le 16
192.0.0.0/3 ge 24 le 24
If you want to match anything in the individual address spaces for class A,
B, C
0.0.0.0/1 le 32
128.0.0.0/2 le 32
192.0.0.0/3 le 32
Class A- binary first bit 0.
Class B - binary first two bits 10.
Class C - binary first three bits 110.
