Rather this:
InetAddress[] IPs = InetAddress.getAllByName(myName);
Peace......

What about doing something like this:
InetAddress me = InetAddress.getLocalHost(); // get the object
InetAddress myName = me.getByName( me.getHostName() ); // lookup my name
InetAddress IPs = InetAddress.getAllByName(myName);
Peace.......

It's not that easy. A host may have several IP addresses and other
hosts may have to use different addresses to reach it. E.g. hosts on
the intranet may have to use 192.168.0.100, but external machines may
have to use 65.123.66.124.
If you have a socket connection to another host you can call
Socket.getLocalAddress() to find out which local address is used for
the socket.
