    On Linux it is just a catch all address (listen on all interfaces)

    Elsewhere it doesn’t do anything since I don’t believe it is part of the networking standards

        If I were implementing it, I’d just list all interfaces on the machine and see if there’s a service bound to it on the given port. There’s probably only one, but it’s technically undefined behavior I think.
