This is a simple application that provides geolocation information based on the user's IP address. It uses the MaxMind GeoLite2 databases to lookup country, city, and ASN details.

• Country lookup: Returns the country name based on the user's IP address.
• City lookup: Returns the city name based on the user's IP address.
• Full JSON endpoint: Returns a comprehensive JSON object containing:
  • IP address
  • Country name and ISO code
  • City name
  • Region name and code
  • Postal code
  • Latitude and longitude
  • Time zone
  • ASN and ASN organization
  • User agent information
• Rate limiting: Limits requests to prevent abuse.
• Dockerized: Easy to deploy using Docker.
• Frontend: Simple HTML page using Bootstrap to display the information.

• Python 3.8
• Flask
• geoip2
• Flask-Limiter
• ipaddress

1. Clone the repository:

   git clone https://github.com/danielvca/ipcountryfinder.git
   

2. Download the MaxMind GeoLite2 databases:

GeoLite2-Country.mmdb

GeoLite2-City.mmdb

GeoLite2-ASN.mmdb

Create a directory called: mdb

Place the .mmdb files in the mdb directory.

3. Build the Docker image:

docker build -t ip-country-finder .

Run the Docker container:

docker run -d -p 5002:5000 --name IPFinder ip-country-finder

Access the application in your browser at http://localhost:5002/.

/country: Returns the country name.

/city: Returns the city name.

/json: Returns the full JSON object.

Rate Limits:
Edit the app.py to set your own limits

You can download the relevant binary databases (.mmdb format) directly from MaxMind using the below link:

Please Note: You will need to create a free account in order to download the files. This solution does not cover automatic database refresh.

The application uses Cloudflare headers (CF-Connecting-IP) to get the real client IP address if available.

The X-Forwarded-For header is used as a fallback if the Cloudflare header is not present.

The user_agent field in the JSON response is parsed to provide basic information.

The HTML page uses JavaScript to fetch and display the data from the /json endpoint.
