What is the difference between the Windows and Linux loopback interface?

I have a WCF service on a Windows 2008 server, that listens on 127.0.0.1:19000, that I am able to connect to externally (i.e. a pc in the same network can ping :9000, and the WCF service will 'hear' the request).

I think in linux that I would have to bind a service to the 0.0.0.0:port address if I wanted to listen externally, and that a 127.0.0.1 address would not be able to listen externally.

Is the above correct? What is the Windows equivalent of the 0.0.0.0 address?

Looking at WireShark, it seems that Linux and Windows implement the loopback interface differently? Why is this and what are those differences?

(Or, if the question doesn't make sense, please tell me why!!)
