if (ASPCountryEmpty)
                {
                    string empty = "<option selected style='display: none' value=''></option>";
                    output.Content.AppendHtml(empty);
                }

For getting the IP, I was trying to balance the 2 variants: downloading GeoIP database (https://dev.maxmind.com/geoip/geoip2/geolite2/) or calling http://freegeoip.net/ .

I do call http://freegeoip.net/ – and the next point is to use Dependency Injection … or a provider to do that.

For the moment, the code is:
