    Question InetAddress.getLocalHost() issue...

    Hello,

    I am using Netbeans 6.7.1 on Fedora 11(Linux). The issue is that when I use InetAddress.getLocalHost() method, I get only the loopback interface IP. In Windows 7, I did same and got the IP that I was having. Right now in spite of being connected to the net and havinga live IP, I can't get that IP using the above mentioned method. Am I doing something wrong?

    Thanks.

    There have been some reported issues with InetAddress.getLocalHost() in the past. If it's causing you trouble, you could try explicitly enumerating the interfaces:

    Java Code:
          Enumeration<NetworkInterface> infs = NetworkInterface.getNetworkInterfaces();
          while (infs.hasMoreElements()) {
            NetworkInterface inf = infs.nextElement();
            System.out.println("Name : " + inf.getName());
            Enumeration<InetAddress> addrs = inf.getInetAddresses();
            while (addrs.hasMoreElements()) {
              System.out.println("  " + addrs.nextElement().getHostAddress());
            }
          }
    N.B. Neither InetAddress.getLocalHost() or NetworkInterface will provide the local IP if the security policy you're running with doesn't allow it. This usually applies to Applets.
