# Geolocation with GeoIP

Deprecated since version 1.9: This module is deprecated in favor of django.contrib.gis.geoip2, which supports IPv6 and the GeoLite2 database format.

The `GeoIP` object is a ctypes wrapper for the MaxMind GeoIP C API. [1]

In order to perform IP-based geolocation, the `GeoIP` object requires the GeoIP C library and either the GeoIP Country or City datasets in binary format (the CSV files will not work!). These datasets may be downloaded from MaxMind. Grab the `GeoLiteCountry/GeoIP.dat.gz` and `GeoLiteCity.dat.gz` files and unzip them in a directory corresponding to what you set `GEOIP_PATH` with in your settings. See the example and reference below for more details.

## Example

Assuming you have the GeoIP C library installed, here is an example of its usage:

    >>> from django.contrib.gis.geoip import GeoIP
    >>> g = GeoIP()
    >>> g.country('google.com')
    {'country_code': 'US', 'country_name': 'United States'}
    >>> g.city('72.14.207.99')
    {'area_code': 650,
    'city': 'Mountain View',
    'country_code': 'US',
    'country_code3': 'USA',
    'country_name': 'United States',
    'dma_code': 807,
    'latitude': 37.419200897216797,
    'longitude': -122.05740356445312,
    'postal_code': '94043',
    'region': 'CA'}
    >>> g.lat_lon('salon.com')
    (37.789798736572266, -122.39420318603516)
    >>> g.lon_lat('uh.edu')
    (-95.415199279785156, 29.77549934387207)
    >>> g.geos('24.124.1.80').wkt
    'POINT (-95.2087020874023438 39.0392990112304688)'

## `GeoIP` Settings

### `GEOIP_PATH`

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

### `GEOIP_LIBRARY_PATH`

A string specifying the location of the GeoIP C library. Typically, this setting is only used if the GeoIP C library is in a non-standard location (e.g., `/home/sue/lib/libGeoIP.so`).

### `GEOIP_COUNTRY`

The basename to use for the GeoIP country data file. Defaults to `'GeoIP.dat'`.

### `GEOIP_CITY`

The basename to use for the GeoIP city data file. Defaults to `'GeoLiteCity.dat'`.

## `GeoIP` API

class `GeoIP`(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 data sets. 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 (.dat) are located. Assumes that both the city and country data sets are located in this directory; overrides the `GEOIP_PATH` settings attribute.
`cache` | The cache settings when opening up the GeoIP datasets, and may be an integer in (0, 1, 2, 4) corresponding to the `GEOIP_STANDARD`, `GEOIP_MEMORY_CACHE`, `GEOIP_CHECK_CACHE`, and `GEOIP_INDEX_CACHE` `GeoIPOptions` C API settings, respectively. Defaults to 0 (`GEOIP_STANDARD`).
`country` | The name of the GeoIP country data file. Defaults to `GeoIP.dat`. Setting this keyword overrides the `GEOIP_COUNTRY` settings attribute.
`city` | The name of the GeoIP city data file. Defaults to `GeoLiteCity.dat`. Setting this keyword overrides the `GEOIP_CITY` settings attribute.

## `GeoIP` Methods

### Querying

All the following querying routines may take either a string IP address or a fully qualified domain name (FQDN). For example, both `'205.186.163.125'` and `'djangoproject.com'` would be valid query parameters.

`GeoIP.``city`(query)

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

`GeoIP.``country`(query)

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

`GeoIP.``country_code`(query)

Returns only the country code corresponding to the query.

`GeoIP.``country_name`(query)

Returns only the country name corresponding to the query.

### Coordinate Retrieval

`GeoIP.``coords`(query)

Returns a coordinate tuple of (longitude, latitude).

`GeoIP.``lon_lat`(query)

Returns a coordinate tuple of (longitude, latitude).

`GeoIP.``lat_lon`(query)

Returns a coordinate tuple of (latitude, longitude),

`GeoIP.``geos`(query)

Returns a `django.contrib.gis.geos.Point` object corresponding to the query.

### Database Information

`GeoIP.``country_info`

This property returns information about the GeoIP country database.

`GeoIP.``city_info`

This property returns information about the GeoIP city database.

`GeoIP.``info`

This property returns information about all GeoIP databases (both city and country), and the version of the GeoIP C library (if supported).

### GeoIP-Python API compatibility methods

These methods exist to ease compatibility with any code using MaxMind’s existing Python API.

classmethod `GeoIP.``open`(path, cache)

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

`GeoIP.``region_by_addr`(query)

`GeoIP.``region_by_name`(query)

`GeoIP.``record_by_addr`(query)

`GeoIP.``record_by_name`(query)

`GeoIP.``country_code_by_addr`(query)

`GeoIP.``country_code_by_name`(query)

`GeoIP.``country_name_by_addr`(query)

`GeoIP.``country_name_by_name`(query)
