Instead of Class A, you could say "addresses in the range 1.0.0.0 - 126.255.255.255" or something, but this could be clumsy and why not use the term that means the same, anyway.
How about just:
0.0.0.0/2 (old 'A' space) 128.0.0.0/2 (old 'B' space) 192.0.0.0/2 (old 'C' space)
Surely 0.0.0.0/1, 128.0.0.0/2, & 192.0.0.0/3 or else you erroneously exclude half the address space formerly classed as `A' (64.0.0.0/2) and include the 224.0.0.0/4 (`Class D'/Multicast) and 240.0.0.0/4 (`Class E') address blocks. How about simply using the phrase `former Class {A,B,C} space' when talking about these ranges, maybe with a note relating these to the 0/1, 128/2 and 193/3 notation.
