Hi, I'm trying to print my IP Address on a window label using C# - it's only a couple of lines of code but prints garbage, almost like a MAC address. I've heard a loop might be needed but I'm assuming it will be the first IP address in AddressList. Here's the code:

private void Form1_Load(object sender, EventArgs e)
       {
           IPHostEntry IPHost = Dns.GetHostEntry(Dns.GetHostName());
           //IPHostEntry IPHost = Dns.GetHostByName();
           lblStatus.Text = "My IP address is " + IPHost.AddressList[0].ToString();
           alSockets = new ArrayList();
           Thread thdListener = new Thread(new ThreadStart(listenerThread));
           thdListener.Start();

       }


Any help much appreciated.

C#
public static bool IsLocalIpAddress(string host)
{
  try
  { // get host IP addresses
    IPAddress[] hostIPs = Dns.GetHostAddresses(host);
    // get local IP addresses
    IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());

    // test if any host IP equals to any local IP or to localhost
    foreach (IPAddress hostIP in hostIPs)
    {
      // is localhost
      if (IPAddress.IsLoopback(hostIP)) return true;
      // is local address
      foreach (IPAddress localIP in localIPs)
      {
        if (hostIP.Equals(localIP)) return true;
      }
    }
  }
  catch { }
  return false;
}
