RE: FW: Ip address question.....

Probably because they thought 32 bits would be enough that would last
forever...kind of like "640K mem should be more than enough..."

While it could be any value, my best guess would be that back then we
were just starting to get into things and had mostly 16-bit processors
and it became an "ease of programming" at the machine code/assembler
level.

Even back then, the assumption was we'd move to a 32-bit processor and
eventually to a 64-bit one. So while they could come up with an address

of semi-infinite length, they probably looked at the machine types and
processing capability of the time and worked within semi-efficient
scopes.

Just my two cents. (That was even before my time) ;)
