Well 1 I use the following code snippet to get ip :

private String getIP()
// This try will give the Public IP Address of the Host.
URL url = new URL("http://automation.www.example.com/n09230945.asp");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String ipAddress = new String();
ipAddress = (in.readLine()).trim();

if (!(ipAddress.length() > 0))
InetAddress ip = InetAddress.getLocalHost();
return ((ip.getHostAddress()).trim());
catch(Exception ex)
return "ERROR";
System.out.println("IP Address is : " + ipAddress);

External ip address can be obtained via http://www.ip-details.com/ too .
