Get IP address of client machine

Question

I am trying to get the IP address of client machine using C#. I am using the below code to get the IP address :

string IPAddress = HttpContext.Current.Request.UserHostAddress;

But it is giving me the response in encoded format i.e fe80::ed13:dee2:127e:1264%13

How can I get the actual IP address? Any one faced this issue please share some idea.

Answer 1

C#

string IPAddress = GetIPAddress();

public string GetIPAddress()
{
    IPHostEntry Host = default(IPHostEntry);
    string Hostname = null;
    Hostname = System.Environment.MachineName;
    Host = Dns.GetHostEntry(Hostname);
    foreach (IPAddress IP in Host.AddressList) {
        if (IP.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) {
            IPAddress = Convert.ToString(IP);
        }
    }
    return IPAddress;
}

VB.net

Dim Host As IPHostEntry
Dim Hostname As String
Hostname = My.Computer.Name
Host = Dns.GetHostEntry(Hostname)
For Each IP As IPAddress In Host.AddressList
    If IP.AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork Then
        IPAddress = Convert.ToString(IP)
    End If
    Next
Return IPAddress

Hope this helps

private string GetUserIP()
 {
     return Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? Request.ServerVariables["REMOTE_ADDR"];    
 }

You may get several ip address, so can split them as-

private string GetUserIP()
    {
        string ipList = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (!string.IsNullOrEmpty(ipList))
        {
            return ipList.Split(',')[0];
        }

        return Request.ServerVariables["REMOTE_ADDR"];
    }
