The project requires the MAC address and IP address of the client, but many examples are found on the Internet. However, after testing, the server code is obtained. Later, I saw an article saying, the client's MAC address cannot be obtained because of the server code running on this webpage.
Below are some of the information we found, but they all get the client

To obtain a remote address, use the sendarp function. The specific code is as follows:
[Dllimport ("iphlpapi. dll")]
Private Static unsafe extern int sendarp (int32 DEST, int32 host, ref intptr Mac, ref intptr length );
[Dllimport ("ws2_32.dll")]
Private Static extern int32 inet_addr (string IP );

If you want to get a remote address, you need to use sendarp this function to implement. The specific code is as follows:

private static unsafe extern int Sendarp (Int32 dest,int32 host,ref IntPtr mac,ref IntPtr length);
[DllImport ("Ws2_32.dll")]
private static extern Int32 inet_addr (string IP);
Int32 ldest= inet_addr ("157.60.68.163");/
