How can i get the LAN IP-address of a computer using Java? I want the IP-address which is connected to the router and the rest of the network.
I've tried something like this:
Socket s = new Socket("www.google.com", 80);
String ip = s.getLocalAddress().getHostAddress();
s.close();
This seem to work on some cases, but sometimes it returns the loopback-address or something completely different. Also, it requires internet connection.
Does anyone got a more accurate method of doing this?
