Nothing wrong with pedantry. However, `4', `6' and `46' aren't in
themselves (or even in this context) class A _addresses_. They are
allocations out of the class A range. 4.4.4.4 - now *that's* a class
A address. :-)

Just because the notation `/8' hadn't been devised when BBN said "we'll
have that one, that one and ... that one" doesn't mean the terminology
cannot be retrospectively applied. It's a bit like saying that ...
(frantically trying to think of a suitable analogy but failing) ...
that the world's first <something> wasn't actually a <something>
because the word <something> hadn't been coined then... :-)
