I differ on the definition of "a lot easier" for number 1. ADDTCPIFC and STRTCPIFC do not seem like "a lot" to me.

As a developer, I can start a server program (for testing) using any
unused port higher than 1024. I don't need any special authorities. I
also don't have to get an IP address assigned.

I don't really understand 2. Not arguing with it, I just don't understand it.

In order to bind to a port from 1-1024 you need to have special
authority. In the unix world, that's restricted to root. I'm not sure
what authorities are needed on IBM i.
