      This is a special case. This resolves to 0.0.0.0, and technically cannot be routed. Some(!) systems use it as a kind of alias for all local network addresses, but it is not a given.

        I’m aware. Conveniently this works on all the systems I’ve tried, making it useful for testing local services (e.g. ssh 0).
