GeoIP

Creates variables with values depending on the client IP address, using the precompiled MaxMind databases or their counterparts.

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

When building from the source code, this module isn't built by default; it should be enabled with the ‑‑with‑http_geoip_module build option.

Important

This module requires the MaxMind GeoIP database or a counterpart such as MaxMind GeoLite2.

Configuration Example

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

geoip_country

Syntax	geoip_country file;
Default	—
Context	http

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".

geoip_city

Syntax	geoip_city file;
Default	—
Context	http

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_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.

geoip_org

Syntax	geoip_org file;
Default	—
Context	http

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".

geoip_proxy

Syntax	geoip_proxy file;
Default	—
Context	http

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.

geoip_proxy_recursive

Syntax	geoip_proxy_recursive on | off;
Default	geoip_proxy_recursive off;
Context	http

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.
