Offtopic but why are people using high port numbers? Additional security due to a nonstandard port? If so, does that go together with anything additional like port knocking? Or is it multiple hosts on the same IP, but different ports?

Some people think that it adds to security. Some people want to reduce noise in logs.

A relatively common use case is multiple devices behind a NAT, where each port goes to a different device.

It's to keep my logs cleaner. It doesn't add any security value since the port is still open. I don't allow password auth. I was just always annoyed with how many times port 22 was getting hit everyday by attackers.
