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
Yeah I'm familiar with that part, I just meant in context of a browser being able to connect to it.
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.
