In discussing addresses larger than 32 bits, remember that those extra
bits pile up additional memory awfully fast.

To build a computer with 48-bit addresses and to give it 2**48 memory
cells, you would need more cells than there are atoms in the Earth.
Addresses bigger than 48 bits are probably not worthwhile, unless you
need a discontiguous (sparse) address space.
