Well, not more than 128 entities *can*, since that's all the class A
address space there is!  (Really, 127, since one of them - 127 - is
reserved for loopback uses.)

Actually, countries don't get address space.  RIRs get address space,
usually in blocks like a /8 or /7, which they break down and assign to
providers (and large end users).  There is no allocation at the country
level.  (There was a time, though, when it seemed Canada might get its
own class A - this was before the current RIR model arose.)

Unless you're talking about a country's government's network presence,
or perhaps if there's a country where IP address assignment is
nationalized (I know of none, but with all the countries out there
there probably are some).
