Just a simple API call e.g. https://ipapi.co/8.8.8.8/country/

US

Here's a C# example with working fiddle :

using System;
using System.Net;
using System.IO;
using System.Text;


public class Program
{
    public static void Main()
    {

      ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

      HttpWebRequest request   = (HttpWebRequest)WebRequest.Create("https://ipapi.co/8.8.8.8/country/");
      HttpWebResponse response = (HttpWebResponse)request.GetResponse();

      var reader = new System.IO.StreamReader(response.GetResponseStream(), ASCIIEncoding.ASCII);
      Console.WriteLine(reader.ReadToEnd());

    }
}
