[Edit:] Code block added

http://freegeoip.net/json/[^]

Request to this url and parse json to get user's country,city,IP ....

Even a simpler solution then you have implemented

string ip = Server.HtmlEncode(Request.UserHostAddress);

XmlDocument doc = new XmlDocument();

string getdetails= "http://www.freegeoip.net/xml/" + ip;

doc.Load(getdetails);

XmlNodeList nodeLstCity = doc.GetElementsByTagName("City");

string location = nodeLstCity[0].InnerText;

I think you had not searched for your problem in CP.
Anyway just visit This[^], This1[^] and This[^] links you will get your solution.

At timezoneapi.io you can request an IP address using cURL. It returns a few objects including location, timezone and datetime.

$curl https://timezoneapi.io/developers/ip-address

Returns
- Location including latitude / longitude
- timezone (time zone variables e.g. capital, currency, phone prefix, shortcodes etc.
- datetime (the date / time for the timezone when the request was made + lots of date / time variables).

Take a look here for API documentation:
IP address. Get users location, time zone and date/time details. - Timezone API[^]
