You can never get the MAC address of a user connected to your website when a socket connection occurs between the destination (your website's server) and a source (client's computer) you can only get the source IP address for the MAC address it's never sent over the socket connection (Client Server) in order to get the IP address of a user: using System.Net; Private string GetIP() { string strHostName = ; strHostName = System.Net.Dns.GetHostName(); IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName); IPAddress[] addr = ipEntry.AddressList; return addr[addr.Length-1].ToString(); }
