This machine is a firewall. One side is connected to the internal 
network. It has address 192.168.1.1 and a fixed hostname 'arwen'.
The other side is an ADSL connection. I get the IP address every time I 
connect. That IP address has one or more DNS names assigned.
This computer is a multi-hosted machine.  It has more than one IP 
addresses. You can see that gethostbyname('arwen') returns '192.168.1.1'
because the host 'arwen' is 192.168.1.1 in my local network. But I need 
to determine the external IP (that connects directly to Internet).

In windows, you can set the computer name which is not the same. It is a 
name of computer in Microsoft Windows Network.
I hope this helps.
