Receive and Parse a broadcasted IP in C#

UDP

Hello,

I am trying to write a C# code that will wait for any broadcasted udp message. This message will be an IP Address. After receiving the message, I want to parse the IP address received and then continue to receive udp packets from that IP Address. I already have working code that can Parse a known IP address and the udp packet sending works fine. But now I need to be able to receive a broadcasted IP and then parse it.

Here is some code I am trying:

Socket newsock = new Socket(AddressFamily.InterNetwork,
               SocketType.Dgram, ProtocolType.Udp);

           IPEndPoint iep = new IPEndPoint(IPAddress.Any, 11000);
           newsock.Bind(iep);
           EndPoint ep = (EndPoint)iep;

           byte[] datip = new byte[1024];
           recv = newsock.ReceiveFrom(datip, ref ep);
           string stringData = Encoding.ASCII.GetString(datip, 0, recv);
           IP_Address.Text = ep.ToString();
           Application.DoEvents();

           IPEndPoint dsender = new IPEndPoint(IPAddress.Parse(IP_Address.Text), 11000);                     //IP address of device. Waits for connection.
           EndPoint tmpRemote = (EndPoint)dsender;  //stores device into variable

Thanks,
