I don't know the C semantics but ususaly you use "bind" to install your 
server socket and as argument you can give an IP address, which will mean 
that you bind *only* to that address. If you want to bind to *all* network 
interfaces you use "INADDR_ANY" (0.0.0.0).

if you have linux try "man 7 ip", "man 2 bind", "man socket"

Yes you do, if you have one ethernet card or dialup. The other address is 
127.0.0.1 and is called "localhost". Its the local loopback device which 
lets you test any network software on the local machine.
