How to install geoip C library

If your os has a system package manager (e.g, on linux, apt of ubuntu, yum of fedora, pacman of arch. MacPorts and homebrew on OSX),

then, there is a very high possibility that there is alreay a geoip c library package inside the repository.

If not, you can build for yourself:

wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP-1.4.7.tar.gz
tar -xvzf GeoIP-1.4.7.tar.gz
cd GeoIP-1.4.7
./configure --prefix=/usr
make
sudo make install

Data

Befor you can use this package, you need to download or buy some data from www.maxmind.com.

There are some free databases among some commercial versions, the free databases can be found here.

Install

[sudo] npm install geoip [-g]

Compatibility

From v0.4.0, geoip need nodejs >= 0.4.0, if you want to use it on old nodejs, you can:

npm install geoip@0.3.4-1

Usage

Check edition

var edition = geoip.check('/path/to/file');

console.log(edition); // output 'country', 'city', 'org'... so on

Create a new instance of sub-module, for example:

var city = new geoip.City('/path/to/GeoLiteCity.dat', false);  // not to cache the database

var city = new geoip.City('/path/to/GeoLiteCity.dat');  // the default option is cache

Update database on the fly:

city.update('/path/to/new/GeoLiteCity.dat');

Modules

Country

ipv4

// Open the country data file
var Country = geoip.Country;

var country = new Country('/path/to/GeoIP.dat');

// Synchronous method(the recommended way):
var country_obj = country.lookupSync('8.8.8.8');

console.log(country_obj);
/*
  { country_code: 'US',
    country_code3: 'USA',
    country_name: 'United States',
    continent_code: 'NA'
  }
*/

// Asynchronous method:
country.lookup('www.google.com', function(err, data) {
    if (err) {throw err;}
    if (data) { // if not found, just return null
        console.log(data);  // same as lookup method
    }
});

ipv6 (Currently only Country module supports ipv6)

// Open the ipv6 edition of country module
var Country6 = geoip.Country6;

var country_v6 = new Country6('/path/to/GeoIPv6.dat');

// Synchronous method
var country_obj_v6 = country_v6.lookupSync('2607:f0d0:1002:0051:0000:0000:0000:0004');

console.log(country_obj_v6); // Same as ipv4
/*
  { country_code: 'US',
    country_code3: 'USA',
    country_name: 'United States',
    continent_code: 'NA'
  }
*/

// Asynchronous method
country_v6.lookup('2400:2352:b0f1:36c5:aa9d:694a:2f98:40bd', function(err, data_v6) {
    if (err) {throw err;}
    if (data_v6) {
        console.log(data_v6);
        /*
         {
           country_code: 'JP',
           country_code3: 'JPN',
           country_name: 'Japan',
           continent_code: 'AS'
          }

        */
    }
});

City

// Open the GeoLiteCity.dat file first.
var City = geoip.City;
var city = new City('/path/to/GeoLiteCity.dat');

Synchronous method:

var city_obj = city.lookupSync('8.8.8.8');
console.log(city_obj);
/*
 Return an object of city information
 {
  "country_code":"US",
  "country_code3":"USA",
  "country_name":"United States",
  "continet_code":"NA",
  "region":"CA",
  "city":"Mountain View",
  "postal_code":"94043",
  "latitude":37.41919999999999,
  "longitude":-122.0574,
  "dma_code":807,
  "metro_code":807,
  "area_code":650
  }
 */

Asynchronous method:

city.lookup('www.google.com', function(err, data) {
    if (err) {throw err;}
    if (data) {
        console.log(data);
    }
});

Organization

var Org = geoip.Org;
var org = new Org('/path/to/file')  // Org module can open three edition database 'org', 'asnum', 'isp'

Synchronous method:

var org_str = org.lookupSync('8.8.8.8');

console.log(org_str);
/*
  The type of returned data is string, for example:

  'Genuity'
  'AS15169 Google Inc.'

  no longer an object
*/

Asynchronous method:

org.lookup('www.google.com', function(err, data) {
    if (err) {throw err;}
    if (data) {
        console.log(data);
    }
});

Region

var Region = geoip.Region;
var region = new Region('/path/to/GeoIPRegion.dat');

Synchronous method:

var region_obj = region.lookupSync('8.8.8.8');

console.log('region_obj);
/*
  region object has two properties:
  { country_code: 'US', region: 'CO' }

*/

Asynchronous method:

region.lookup('www.google.com', function(err, data) {
    if (err) {throw err;}
    if (data) {
      console.log(data);
    }
});

NetSpeed

var NetSpeed = geoip.NetSpeed;
var netspeed = new NetSpeed('/path/to/GeoIPNetSpeed.dat');

Synchronous method:

var netspeed_str = netspeed.lookupSync('8.8.8.8');

console.log(netspeed_str);
/*
  netspeed_str just a simple string, 'Dialup', 'Corprate'... so on
*/

Asynchronous method:

netspeed.lookup('www.google.com', function(err, data) {
    if (err) {throw err;}
    if (data) {
      console.log(data);  // Maybe return 'unknow' or different from lookup method
    }
});
