RE: Proposal for Temporary Special Class A Space Guidelines
Hi,
. I'm slightly unhappy with the frequent use of the terms "class A" and "class C". I think we are trying for a while now to sort of phase-out the usage of these terms. So I'd prefer to
- clearly qualify the usage of these terms as obsolete, or "old classful terminology",
- wherever possible, please replace "class x" with the appropriate address range. I think this would make the paper more obvious anyway.
Not an easy one. Sure, you can put the offending terms in quotes, as Wilfried does, to indicate disdain for this old politically incorrect terminology. But there's no getting away from the fact that when you say Class A in the document, you really mean Class A and not /8 - you don't mean that 196.0.0.0/8, for example, comes under the heading of Class A for the purposes of special allocation.
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) Cheers john

Except that the original allocations were: Class A: 0.0.0.0/1 (I am ignoring the issues of 0.0.0.0/8 and 127.0.0.0/8) Class B: 128.0.0.0/2 Class C: 192.0.0.0/3 Class D: 224.0.0.0/4 Class E: 240.0.0.0/4 (I think it was /4 and not /5) -- Clive D.W.

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.

Why not leave it as it used to be, but just add the "/" notation since most people still refer to the "Class" IP addresses. It would avoid confusion, and everybody knows what you mean when you refer to a network with the / notation. Ronald Kraaijer At 11:22 AM +0100 3/7/97, Yves Devillers wrote:
