Not all networking protocols differentiate between a hardware address and
a network address. The ISO model does not define such a difference.

I think you are trying to define the ISO model in terms of how TCP/IP
works. You need to go the other way. The ISO model defines how a
protocol stack works. We need to map TCP/IP into that model.
