Module ngx_http_geoip_module

• Example Configuration
• Directives
• geoip_country
• geoip_city
• geoip_org
• geoip_proxy
• geoip_proxy_recursive

The ngx_http_geoip_module module (0.8.6+) creates variables with values depending on the client IP address, using the precompiled MaxMind databases.

When using the databases with IPv6 support (1.3.12, 1.2.7), IPv4 addresses are looked up as IPv4-mapped IPv6 addresses.

This module is not built by default, it should be enabled with the --with-http_geoip_module configuration parameter.

This module requires the MaxMind GeoIP library.

Example Configuration

http {
    geoip_country         GeoIP.dat;
    geoip_city            GeoLiteCity.dat;
    geoip_proxy           192.168.100.0/24;
    geoip_proxy           2001:0db8::/32;
    geoip_proxy_recursive on;
    ...

Directives

Specifies a database used to determine the country depending on the client IP address. The following variables are available when using this database:

$geoip_country_code

two-letter country code, for example, “RU”, “US”.

$geoip_country_code3

three-letter country code, for example, “RUS”, “USA”.

$geoip_country_name

country name, for example, “Russian Federation”, “United States”.

Specifies a database used to determine the country, region, and city depending on the client IP address. The following variables are available when using this database:

$geoip_area_code

telephone area code (US only).

This variable may contain outdated information since the corresponding database field is deprecated.

$geoip_city_continent_code

two-letter continent code, for example, “EU”, “NA”.

$geoip_city_country_code

two-letter country code, for example, “RU”, “US”.

$geoip_city_country_code3

three-letter country code, for example, “RUS”, “USA”.

$geoip_city_country_name

country name, for example, “Russian Federation”, “United States”.

$geoip_dma_code

DMA region code in US (also known as “metro code”), according to the geotargeting in Google AdWords API.

$geoip_latitude

latitude.

$geoip_longitude

longitude.

$geoip_region

two-symbol country region code (region, territory, state, province, federal land and the like), for example, “48”, “DC”.

$geoip_region_name

country region name (region, territory, state, province, federal land and the like), for example, “Moscow City”, “District of Columbia”.

$geoip_city

city name, for example, “Moscow”, “Washington”.

$geoip_postal_code

postal code.

Specifies a database used to determine the organization depending on the client IP address. The following variable is available when using this database:

$geoip_org

organization name, for example, “The University of Melbourne”.

Defines trusted addresses. When a request comes from a trusted address, an address from the “X-Forwarded-For” request header field will be used instead.

If recursive search is disabled then instead of the original client address that matches one of the trusted addresses, the last address sent in “X-Forwarded-For” will be used. If recursive search is enabled then instead of the original client address that matches one of the trusted addresses, the last non-trusted address sent in “X-Forwarded-For” will be used.
