Telize is a REST API built on Nginx and Lua allowing to get a visitor IP address and to query location information from any IP address. It outputs JSON-encoded IP geolocation data, and supports both JSON and JSONP.

Geolocation operations are performed using Nginx GeoIP module which caches the database in RAM. Therefore, Telize has very minimal overhead and should be blazing fast.


Nginx modules

Telize requires Nginx 1.7.4+ compiled with the following modules :

If you are using Debian stable, the nginx-extras package have these modules compiled-in.

For maximum performance, please make sure the HttpLuaModule is compiled against LuaJIT :

ldd $(which nginx) | grep lua

Lua modules

Telize requires the following Lua module :

  • Lua CJSON
  • Lua iconv

Installing via LuaRocks :

luarocks install lua-cjson
luarocks install lua-iconv

Alternatively, those modules can be installed directly using binary packages.

GeoIP databases

Telize requires the free GeoLite databases :

For IPv4 support only :

mkdir -p /usr/share/GeoIP
cd /usr/share/GeoIP
gunzip *gz

For IPv4 and IPv6 support :

mkdir -p /usr/share/GeoIP
cd /usr/share/GeoIP
gunzip *gz


Copy timezone.conf and timezone-offset.conf in the Nginx configuration files directory.

Edit nginx.conf to include timezone.conf, timezone-offset.conf and to add directives specifying the path to the GeoIP database files, within the http block.

For IPv4 support only

http {


    include        /etc/nginx/timezone.conf;
    include        /etc/nginx/timezone-offset.conf;

    geoip_country  /usr/share/GeoIP/GeoIP.dat;
    geoip_city     /usr/share/GeoIP/GeoLiteCity.dat;
    geoip_org      /usr/share/GeoIP/GeoIPASNum.dat;

For IPv4 and IPv6 support (requires at least Nginx 1.3.12)

http {


    include        /etc/nginx/timezone.conf;
    include        /etc/nginx/timezone-offset.conf;

    geoip_country  /usr/share/GeoIP/GeoIPv6.dat;
    geoip_city     /usr/share/GeoIP/GeoLiteCityv6.dat;
    geoip_org      /usr/share/GeoIP/GeoIPASNumv6.dat;

Then deploy the API configuration file telize to the appropriate location on your system, and reload Nginx configuration. If you are behind a load balancer, read the next section.

Depending on existing configuration, the map_hash_max_size and map_hash_bucket_size sizes might be set too low and Nginx will refuse to start. If this happens, please add the following directives in the http block.

map_hash_max_size 8192;
map_hash_bucket_size 64;

On busy instances, the maximum number of open files limit must be increased using the worker_rlimit_nofile directive in order to avoid running out of available file descriptors.

Access and Error logs

The default Telize configuration does not have logging enabled, it must be configured manually.

If your Telize instance produces lots of logs, this might be of interest : Log rotation directly within Nginx configuration file.

Telize and Load Balancers

When using Telize behind a load balancer, uncomment the following directives in the server block and set the load balancer IP range accordingly :

# set_real_ip_from; # Put your load balancer IP range here
# real_ip_header X-Forwarded-For;

In the /geoip location, replace this directive :

proxy_set_header X-Real-IP $ip;

By the following directive :

proxy_set_header X-Forwarded-For $ip;

CORS Support (Cross-origin resource sharing)

Telize has CORS enabled by default since version 1.02. The following variables defines CORS behavior, within the telize configuration file.

set $cors "true";
set $cors_origin "*";


For complete API documentation and JavaScript API usage examples, please check the project site :

Get IP address in Plain text format

Get IP address in JSON format

Get IP address location in JSON format

Calling the API endpoint without any parameter will return the visitor IP address :

Appending an IP address as parameter will return location information for this IP address :
