//方法一HttpContext.Current.Request.UserHostAddress; //方法二HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];//方法三string strHostName = System.Net.Dns.GetHostName();string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString();//方法四（无视代理）HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

服务端：

//方法五var ip = '<!--#echo var="REMOTE_ADDR"-->';alert("Your IP address is "+ip);//方法六（无视代理）function GetLocalIPAddress() {     var obj = null;     var rslt = "";     try     {         obj = new ActiveXObject("rcbdyctl.Setting");         rslt = obj.GetIPAddress;         obj = null;     }     catch(e)     {         //     }    return rslt; }

客户端：

if(Context.Request.ServerVariables["HTTP_VIA"]!=null) // using proxy{      ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();  // Return real client IP.}else// not using proxy or can't get the Client IP{      ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString(); //While it can't get the Client IP, it will return proxy IP.}
