Not terribly relevant to my original point, but: I want to be able to
individually address every machine on a single worldwide network running IP.
How do I do this without a unique IP address for each machine?
Nothing prevents you from assigning a unique IP address to each machine.
However, this doesn't mean that every IP address in the world uniquely
identifies a single machine. There are all sorts of ways IP addresses can be
shared by multiple machines which you may or may not choose to use.
