Sorry, I mistyped when I said WideView server, what I meant was the WideFS server.
When your server opens a Port, and you do NOT specify a specific interface (ip address) or you specify ANY (the default), then the socket is bound to the port on ANY address that is on the machine (local computer) That means if you have 192.168.21.100 , and 192.168.22.100 (two nic's whether on the same subnet or not) your Port (9000 ) would be bound to both. IF, however, you specify a specific address on the socket bind, then the socket/port will only be bound to that Specific address.
This is how you can have mutliple HTTP servers on the same machine both listening on port 80, but on different Interfaces.
So when you define the socket and specify the port, you can also specify a discrete IP addess
