Because he is attempting to use a zero subnet (10.150.0.0/24 by the end of
my response) ?

Yes, he could use a different portion of the class A to subnet the first
floor. He has plenty of addresses. But that wasn't the question.

Of course, but that was not the question asked.

It sounded to me as though he wants to route between the floors. If so, how
will using the scheme in his question work? Either he is going to have to
change the first floor to a /24 (add 8 bits like I said) or he will have to
change the other floors to a /16 and bridge everything together.

Yes. More specifics are always helpful.
If I am wrong about how this works, please point out where. I am always
willing to learn something new - that's why I subscribe to this group.
