All of this would use up 6 bits and still leave 17 for any other
purposes you have in mind (assuming codes from 127.0.0.2 to 127.0.0.126).
Uses up 6 of the 7 bits in that range, Paul. Did you mean 127.0.0.2
through 127.255.255.254?
{o.o}
No I meant 127.0.0.2 to 127.0.0.126; The bitmask '6' would check
the "bad" bits; '24' the "good" bits; '32' for "well-known"; And '64'
for a recent offender. The bottom bit can't be safely used if it can
be set alone (i.e. result in 127.0.0.1) and the top bit isn't needed.
Using the #1 bit (value 2) for any purpose is just redundant and not
needed. (Using bit numbering starting at zero, and drawing little
endian for all of the programmers brought up on Intel documentation.)
So I really did mean the 6 bits as below (warning ASCII art)
128 64 32 16 8 4 2 1
-------------------------------------------------------------------
unused recent well-known (good bits) (bad bits) unusable
OK you meant 2 to 126 was used not that the ultimately usable bits
extends over that range, which is what I had read your statement to
mean. I took the parenthetical expression to be referring to the
"17 for any other purposes" as opposed to the "6 bits" used up.
