I once calculated that there were sufficient IPv6 addresses (another
128 bit quantity) to provide a distinct address for every cluster of
about 10^12 atoms within planet Earth. 10^12 atoms sounds like quite
a lot, but it is much smaller than a typical bacterium and a hell of a
lot smaller than any transistor ever manufactured: even if you
converted the entire planet into a data storage system, you wouldn't
have enough matter to build a filesystem that big, let alone power
supplies, cabling, support structures etc.
Cheers,
Matthew
