            {
                String command = "cmd.exe /c ipconfig /all";
                Process p = Runtime.getRuntime().exec(command);
                BufferedReader br =

                while ((line = br.readLine()) != null)
                {
                    if (line.indexOf("Physical Address") > 0)
                    {
                        int index = line.indexOf(":");
