    Bind IP-Endpoint to Socket

    Hello everyone,

    on my local network, there is a udp broadcast sent by a server every 5 seconds. It is 120 Byte long.
    I am trying to set a socket in order to consume it:

    IPAddress ip = IPAddress.Parse("");
    IPEndPoint ipe = new IPEndPoint(ip, 55555);
    Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp)
        ReceiveBufferSize = 120 
    socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, 30);
    My local cmd -> /ipconfig shows the following:

    Unfortunately, I am getting error message in the binding line:

    System.Net.Sockets.SocketException: The requested address is not valid in this context
    What could be the problem? Wrong IP format? Or am I doing something wrong when instantiating?

    Would be really happy if someone could help me anyhow.

    Best regards

    Unfortunately I shared the wrong picture I am sorry. My cmd -> /ipconfig-settings are as follows:

    Use IPAddress.Any instead. The code can also be simplified with UdpClient class:
    var client = new UdpClient(55555);
    client.Client.ReceiveBufferSize = 120;
    [xcode=c#] code here [/xcode] - see bbcode list or use formatting buttons in posting editor.
