(or perhaps not diminished at all). However, in reality, dividing the
field in this way may reduce the address space by a factor of as much
as nineteen orders of magnitude. Again and again, engineers make this
mistake, and render large parts of an address space unusable through
careless, bit-wise allocation of addresses in advance.
The 48-bit addresses in IEEE/L2 protocols are divided in half as
well as have a couple bits set aside to denote local/global scope and
unicast/multicast addresses. It seems to have worked out pretty well.
