I have system with devices sending information to server by TCP sockets and I want to filter devices by MAC address on server app.

I tried to find possibilities to call on socket method to get mac address of sender but I dont see in docs. I suspect that C# app doesn't see ethernet layer info.

If I'm right then which way I should go to checking senders?

Thank you

communication is only inside LAN - server and clients in the same address pool. – user1253359 Sep 14 '20 at 18:40
Sockets don't provide MAC address information. See duplicate for what does. – Peter Duniho Sep 14 '20 at 18:43
