A question about scope in a BB program

Let’s say if there’s only 1 domain in a program.
The domain resolves to an IP and we do a port scan on it.

If there are 20 open ports and every one of them has a vulnerable service running, example an admin panel

  1. Are all those 20 ports/ services inside our scope?

  2. Also is this why Hunters run port scans on all IPs that they find?
