You know, I've felt the same irritation before, but one thing I am wondering
and perhaps some folks around here have been around long enough to know -
what was the original thinking behind doing those /8s?
I understand that they were A classes and assigned to large companies, etc.
but was it just not believed there would be more than 126(-ish) of these
entities at the time? Or was it thought we would move on to larger address
space before we did? Or was it that things were just more free-flowing back
in the day? Why were A classes even created? RFC 791 at least doesn't seem
to provide much insight as to the 'whys'.
