"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi ITsolutionWizard;

First to let you know in advance I am not a Web developer and so I am not sure that this is the most efficient way to code this. The below code snippet should work from your master page. Although it may not work from a development machine using the development web server because it is using localhost as the IP Address. This code also uses Newtonsoft.Json API and can be gotten from NuGet package manager.

using Newtonsoft.Json;

protected void Page_Load(object sender, EventArgs e)
        // Get Request object
        HttpRequest request = base.Request;
        // Get Responce object
        HttpResponse responce = base.Response;

        // Get UserHostAddress property.
        string address = request.UserHostAddress;

        var data = GetIPData<IPData>("" + address + "/json");

        if (data.ip != null)
            string info = String.Format("IP : {0}   County : {1}", data.ip,;
            responce.Write("No information found");


private static T GetIPData<T>(string url) where T : new()
    using (var webData = new WebClient())
        var jsonData = string.Empty;

            jsonData = webData.DownloadString(url);
        catch (Exception ex)
            return new T();
        return !string.IsNullOrEmpty(jsonData)
                    ? JsonConvert.DeserializeObject<T>(jsonData)
                    : new T();

// Used to deserialize Json object
public class IPData 
    public string ip { get; set; }
    public string hostname { get; set; }
    public string loc { get; set; }
    public string org { get; set; }
    public string city { get; set; }
    public string region { get; set; }
    public string country { get; set; }
    public int phone { get; set; }

Here is the developer web page for the API used in the above code.

To your statement, "How can I get the country only", change this line of code, "string info = String.Format("IP : {0}   County : {1}", data.ip,;", to this, "string info =;".

 To your statement, "Mine returns :::0. and when I go to I got", If you implemented my code as I posted it I can only assume that you are running this off of your development machine and using the development web server. I stated in my original post to this as follows, "Although it may not work from a development machine using the development web server because it is using localhost as the IP Address", therefor you need to run the Web App on a system that will return an actual IP address and not the word "localhost" which is a mapping to the local machine.
