That's what I assumed, and what Wikipedia shows. OTOH I received a private reply saying
that ports must be unique across an entire server. I guess I'll build a test and find out.

Assuming you have a machine that has IP addresses 192.168.1.1 &
192.168.1.2 assigned...

You can have one application bind itself to port 192.168.1.1:5000 and
another application bind itself to port 192.168.1.2:5000.

However, if your application binds itself to ALL IP's on port 5000
(0.0.0.0:5000) no other application can bind itself to port 5000 on
any IP.
