Quite so.  And if you use names in place of IP addresses, this means that every
name must resolve to exactly one machine, worldwide--which rules out local
interpretations of names.

However this does not prevent machines from
sharing IP addresses ALSO.

If each machine has a unique address, shared addresses are irrelevant.  If
shared addresses are used in place of unique addresses, then the criterion of
unique addressing is not satisfied.
