Socket.bind到所有ips-提供了无效的参数

Question

I want to bind the socket to all the IP addresses available on the machine using:

  mainSocket.Bind(new IPEndPoint(IPAddress.Parse("0.0.0.0"), 0)); //or IPAddress.Any

but I get an An invalid argument was supplied on

 mainSocket.IOControl(IOControlCode.ReceiveAll, byTrue, byOut);

Instead, when I specify the IP, it works just fine.

Ok maybe that's impossible to achieve. But how about detecting which internet interface is being used to connect to internet and getting it's ip? (assuming user is behind NAT / router)

Answer 1

I think it's not possible. Operation with sockets has limitations according to this document TCP/IP Raw Sockets
