Hi All
i am using System.Net, for getting the ip of system the code is given below:

C#

public string getip()
 {
     IPHostEntry host;
     string localIP = "?";
     host = Dns.GetHostEntry(Dns.GetHostName());
     foreach (IPAddress ip in host.AddressList)
     {
         if (ip.AddressFamily.ToString() == "InterNetwork")
         {
             localIP = ip.ToString();
         }
     } return (localIP);
 }

i am getting the right ip when i am running my application on localhost but when i am hosting this application on server, it given the ip of hosted server.

please suggest me, how to get ip of client machine when application is deploy on server.

C#

public static string getclientIP()
{
    string result= string.Empty;
    string ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (!string.IsNullOrEmpty(ip))
    {
        string[] ipRange = ip.Split(',');
        int le = ipRange.Length - 1;
        result = ipRange[0];
    }
    else
    {
        result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
    }
 
    return result;
}

If u run u will get the ip address 127.0.0.1.Here 127.0.0.1 is localhost. this means you are working on your PC. If you try other PC to use your app, you will get a different ip address.what i mean is host your application in your IIS or on your server and another pc must use your application. with that, you will get a different IP. 127.0.0.1 is localhost, meaning, current IP address.

The following example demonstrates how to find out the visitor's browser type, IP address, and more:

XML

<html>
 <body>
 <p>
 <b>You are browsing this site with:</b>
 <%Response.Write(Request.ServerVariables("http_user_agent"))%>
 </p>
 <p>
 <b>Your IP address is:</b>
 <%Response.Write(Request.ServerVariables("remote_addr"))%>
 </p>
 <p>
 <b>The DNS lookup of the IP address is:</b>
 <%Response.Write(Request.ServerVariables("remote_host"))%>
 </p>
 <p>
 <b>The method used to call the page:</b>
 <%Response.Write(Request.ServerVariables("request_method"))%>
 </p>
 <p>
 <b>The server's domain name:</b>
 <%Response.Write(Request.ServerVariables("server_name"))%>
 </p>
 <p>
 <b>The server's port:</b>
 <%Response.Write(Request.ServerVariables("server_port"))%>
 </p>
 <p>
 <b>The server's software:</b>
 <%Response.Write(Request.ServerVariables("server_software"))%>
 </p>
 </body>
 </html>

REMOTE_ADDR and HTTP_X_FORWARDED_FOR are the two server variables we are interested in in order to attempt to capture a users IP address.
as

object UserIPAddress = null;
UserIPAddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR");
if (string.IsNullOrEmpty(UserIPAddress)) {
	UserIPAddress = Request.ServerVariables("REMOTE_ADDR");

The reason we look for the HTTP_X_FORWARDED_FOR value 1st is because of proxy servers and things of that nature as many users are behind one. If that value is not there we just grab the REMOTE_ADDR. Even by doing this there are going to be times when we do not get an IP Address or what we get is not accurate.

Solution 4

public static string GetIPAddress()
{
	System.Web.HttpContext context = System.Web.HttpContext.Current;
	string sIPAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
	if (string.IsNullOrEmpty(sIPAddress)) {
		return context.Request.ServerVariables["REMOTE_ADDR"];
	} else {
		string[] ipArray = sIPAddress.Split(new Char[] { ',' });
		return ipArray[0];
	}
}
