# Geolocation with GeoIP2

The `GeoIP2` object is a wrapper for the MaxMind geoip2 Python library. [1]

In order to perform IP-based geolocation, the `GeoIP2` object requires the geoip2 Python package and the GeoIP `Country` and/or `City` datasets in binary format (the CSV files will not work!), downloaded from e.g. MaxMind or DB-IP websites. Grab the `GeoLite2-Country.mmdb.gz` and `GeoLite2-City.mmdb.gz` files and unzip them in a directory corresponding to the `GEOIP_PATH` setting.

Additionally, it is recommended to install the libmaxminddb C library, so that `geoip2` can leverage the C library’s faster speed.

## Example

Here is an example of its usage:

    >>> from django.contrib.gis.geoip2 import GeoIP2
    >>> g = GeoIP2()
    >>> g.country("google.com")
    {'continent_code': 'NA',
     'continent_name': 'North America',
     'country_code': 'US',
     'country_name': 'United States',
     'is_in_european_union': False}
    >>> g.city("72.14.207.99")
    {'accuracy_radius': 1000,
     'city': 'Mountain View',
     'continent_code': 'NA',
     'continent_name': 'North America',
     'country_code': 'US',
     'country_name': 'United States',
     'is_in_european_union': False,
     'latitude': 37.419200897216797,
     'longitude': -122.05740356445312,
     'metro_code': 807,
     'postal_code': '94043',
     'region_code': 'CA',
     'region_name': 'California',
     'time_zone': 'America/Los_Angeles',
     'dma_code': 807,
     'region': 'CA'}
    >>> g.lat_lon("salon.com")
    (39.0437, -77.4875)
    >>> g.lon_lat("uh.edu")
    (-95.4342, 29.834)
    >>> g.geos("24.124.1.80").wkt
    'POINT (-97 38)'

## API Reference

class GeoIP2(path=None, cache=0, country=None, city=None)

The `GeoIP` object does not require any parameters to use the default settings. However, at the very least the `GEOIP_PATH` setting should be set with the path of the location of your GeoIP datasets. The following initialization keywords may be used to customize any of the defaults.

Keyword Arguments | Description
--- | ---
`path` | Base directory to where GeoIP data is located or the full path to where the city or country data files (`.mmdb`) are located. Assumes that both the city and country datasets are located in this directory; overrides the `GEOIP_PATH` setting.
`cache` | The cache settings when opening up the GeoIP datasets. May be an integer in (0, 1, 2, 4, 8) corresponding to the `MODE_AUTO`, `MODE_MMAP_EXT`, `MODE_MMAP`, and `GEOIP_INDEX_CACHE` `MODE_MEMORY` C API settings, respectively. Defaults to 0 (`MODE_AUTO`).
`country` | The name of the GeoIP country data file. Defaults to `GeoLite2-Country.mmdb`. Setting this keyword overrides the `GEOIP_COUNTRY` setting.
`city` | The name of the GeoIP city data file. Defaults to `GeoLite2-City.mmdb`. Setting this keyword overrides the `GEOIP_CITY` setting.

## Methods

### Instantiating

classmethod GeoIP2.open(path, cache)

This classmethod instantiates the GeoIP object from the given database path and given cache setting.

Deprecated since version 5.1: Use the `GeoIP2()` constructor instead.

### Querying

All the following querying routines may take an instance of `IPv4Address` or `IPv6Address`, a string IP address, or a fully qualified domain name (FQDN). For example, `IPv4Address("205.186.163.125")`, `"205.186.163.125"`, and `"djangoproject.com"` would all be valid query parameters.

GeoIP2.city(query)

Returns a dictionary of city information for the given query. Some of the values in the dictionary may be undefined (`None`).

GeoIP2.country(query)

Returns a dictionary with the country code and country for the given query.

GeoIP2.country_code(query)

Returns the country code corresponding to the query.

GeoIP2.country_name(query)

Returns the country name corresponding to the query.

### Coordinate Retrieval

GeoIP2.coords(query)

Returns a coordinate tuple of (longitude, latitude).

Deprecated since version 5.1: Use `GeoIP2.lon_lat()` instead.

GeoIP2.lon_lat(query)

Returns a coordinate tuple of (longitude, latitude).

GeoIP2.lat_lon(query)

Returns a coordinate tuple of (latitude, longitude),

GeoIP2.geos(query)

Returns a `Point` object corresponding to the query.

## Settings

### `GEOIP_PATH`

A string or `pathlib.Path` specifying the directory where the GeoIP data files are located. This setting is required unless manually specified with `path` keyword when initializing the `GeoIP2` object.

### `GEOIP_COUNTRY`

The basename to use for the GeoIP country data file. Defaults to `'GeoLite2-Country.mmdb'`.

### `GEOIP_CITY`

The basename to use for the GeoIP city data file. Defaults to `'GeoLite2-City.mmdb'`.

## Exceptions

exception GeoIP2Exception

  The exception raised when an error occurs in the `GeoIP2` wrapper. Exceptions from the underlying `geoip2` library are passed through unchanged.
