# mmdb-server

mmdb-server is an open source fast API server to lookup IP addresses for their geographic location. The server can be used with any [MaxMind DB File Format](https://maxmind.github.io/MaxMind-DB/) or file in the same format.

mmdb-server includes a free and open [GeoOpen-Country database](https://data.public.lu/fr/datasets/geo-open-ip-address-geolocation-per-country-in-mmdb-format/) for IPv4 and IPv6 addresses. The file GeoOpen-Country is generated on a regular basis from AS announces and their respective whois records.

# Installation

Python 3.8+ is required to run the mmdb-server with some [additional requirements](./REQUIREMENTS).

- `pip3 install -r REQUIREMENTS`
- `cp ./etc/server.conf.sample ./etc/server.conf`
- `cd bin; python3 server.py`

# Output format

The output format is an array of JSON object (to support the ability to serve multiple geo location database).  Each JSON object of the JSON array includes a `meta`, `country`, `ip` and `country_info` fields. The `country` give the geographic location of the IP address queried. The `meta` field includes the origin of the MMDB database which the the metadata. `ip` returns the queried IP address. `country_info` gives additional information about the country such as `Country`, `Alpha-2 code`, `Alpha-3 code`, `Numeric code`, Latitude and Longitude (average centric value).
