               strHostName = System.Net.Dns.GetHostName();
               IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);
               IPAddress[] addr = ipEntry.AddressList;
               ip = addr[addr.Length - 1].ToString();

    if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
    {
        VisitorsIPAddr = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
    }
    else if (HttpContext.Current.Request.UserHostAddress.Length != 0)

I already tried this method.It's also returning server ip.When we test from local system it returns ip but if I deployed in server it returns server ip.

If you don't get the right IP other network restrictions might prevent it

I have tried with this
string ipaddress;
ipaddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (ipaddress == "" || ipaddress == null)
ipaddress = Request.ServerVariables["REMOTE_ADDR"];

it gives result as ::1

have you tested the functionality against addresses as www.microsoft.com etc?
Sometimes routers prevent giving this information during a request.

Try this,

C#

protected string GetIPAddress()
{
    System.Web.HttpContext context = System.Web.HttpContext.Current;
    string ipAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

    if (!string.IsNullOrEmpty(ipAddress))
    {
        string[] addresses = ipAddress.Split(',');
        if (addresses.Length != 0)
        {
            return addresses[0];
        }
    }

    return context.Request.ServerVariables["REMOTE_ADDR"];
}
