I developed site. I need to get IP of site visitors.
I try to use Request, but it have only internal IP:
Response.Write(Request.ServerVariables["REMOTE_ADDR"]);
I looked all keys in Server Variables collection - the same result:
foreach (string var in Request.ServerVariables)
{
Response.Write(Request[var]);
}
How can I get external IP address?
You can use it to get External (public) IP Address..
public static string getExternalIp()
{
try
{
string externalIP;
externalIP = (new WebClient()).DownloadString("http://checkip.dyndns.org/");
externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
.Matches(externalIP)[0].ToString();
return externalIP;
}
catch { return null; }
}
This it part of my implementation for WebTracking. So here you go a snippet for IpAddress retrieval. You can read more about the Server Variables at Wikipedia.
/// <summary>
/// Get ip address from request
/// </summary>
/// <param name="request"></param>
/// <returns></returns>
private string GetIpAddress(HttpRequest request)
{
if (request.ServerVariables.IsNull()) return null;
var _realAddress = request.ServerVariables[@"HTTP_X_FORWARDED_FOR"];
if (_realAddress.IsNullOrEmpty())
{
_realAddress = request.ServerVariables[@"HTTP_FORWARDED"];
}
if (_realAddress.IsNullOrEmpty())
{
_realAddress = request.ServerVariables[@"REMOTE_ADDR"];
}
return _realAddress;
}
Are you behind a load-balancer/proxy? If so, inspect the headers collection of the request for headers similar to X-FORWARDED-FOR
.
You can use like this
String lstrIpAddress;
if (Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null || Request.ServerVariables["HTTP_CLIENT_IP"] != null)
lstrIpAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
else
lstrIpAddress = Request.ServerVariables["REMOTE_ADDR"];
you can simply use this nuget package.

easy and simple. here is an example :
// Get Public IP
var ip = IPK.GetMyPublicIp();
//Get all IP infos
var IPinfo = IPK.GetIpInfo(ip);
//print some info
Console.WriteLine("*--------------------------- IPK -----------------------------*");
Console.WriteLine("My public IP : " + IPinfo.IP);
Console.WriteLine();
Console.WriteLine("My ISP : " + IPinfo.isp);
Console.WriteLine();
Console.WriteLine("My Country : " + IPinfo.country);
Console.WriteLine();
Console.WriteLine("My Languages : ");
foreach (var lang in IPinfo.languages)
{
Console.WriteLine(" " + lang.Key + " : " + lang.Value);
}
Console.WriteLine("*-------------------------------------------------------------*");
Console.Read();
