These modules are all compiled into Nginx by default unless a module is manually specified to be excluded in configure.

This module creates variables whose values depend on the IP address of the client:
The following example:

Geo $geo {default 0; 127.0.0.1/32 2; 192.168.1.0/24 1; 10.1.0.0/16 1;}

Instructions

Geo

Syntax: Geo [$IP _variable] $variable {...}
Default value: None
Working with Fields: HTTP
This directive specifies the country to which the client IP belongs, and by default it looks for the $remote_addr variable, but it can be specified manually after version 0.7.27.

Geo $arg _remote_addr $geo {...;}

Using CIDR address format, in addition, there are 4 special parameters:

Delete-Deletes the specified network (0.7.23) Default-replaces some undefined addresses with 0.0.0.0/0. Include-a text file with address information that can contain multiple. Proxy-Specifies the proxy server address (0.8.7). Ranges-Specifies that the address (0.7.23) be defined using the form of an address pool, which must be placed first. Geo $country {default no; include conf/geo.conf; 127.0.0.0/24 us; 127.0.0.1/32 ru; 10.1.0.0/16 ru; 192.168.1.0/24 UK;}

conf/geo.conf File Contents:

10.2.0.0/16 Ru; 192.168.2.0/24 Ru;

The value will use the largest parameter, for example, 127.0.0.1 will be "ru" instead of "us".
An example of using ranges:

Geo $country {ranges; default no; 127.0.0.0-127.0.0.0 us; 127.0.0.1-127.0.0.1 Ru; 127.0.0.1-127.0.0.255 us; 10.1.0.0-10.1.255.255 Ru; 192.168.1.0-192.168.1.255 UK; }
