GeoIp

Retreive the geolocation of an IP address based on the ipinfodb.com webservice.

As of 8th November 2010, the service is asking that all users register for an API key.

Consider making a donation to ipinfodb.com at http://ipinfodb.com/donate.php.

Usage

Set API key

GeoIp.api_key = 'YOUR_API_KEY'

This must be done before making the geolocation call.

Retrieve geolocation

GeoIp.geolocation(ip_address)

Example

# 209.85.227.104 = google.be (US)
GeoIp.geolocation('209.85.227.104')

returns:

{
  :status_code    => "OK",
  :status_message => "",
  :ip             => "209.85.227.104"
  :country_code   => "US",
  :country_name   => "UNITED STATES",
  :region_name    => "CALIFORNIA",
  :city           => "MONTEREY PARK",
  :zip_code       => "91754",
  :latitude       => "34.0505",
  :longitude      => "-118.13"
}

Country only

There is an option to only retreive the country information and thus excluding the city details. This results in a faster response from the service since less queries need to be done.

GeoIp.geolocation('209.85.227.104', :precision => :country)

returns:

{
  :status_code    => "OK",
  :status_message => "",
  :ip             => "209.85.227.104"
  :country_code   => "US",
  :country_name   => "UNITED STATES"
}

Timezone information

There is an option now to retrieve optional timezone information too:

GeoIp.geolocation('209.85.227.104', :timezone => true)

returns:

{
  :status_code    => "OK",
  :status_message => "",
  :ip             => "209.85.227.104"
  :country_code   => "US",
  :country_name   => "UNITED STATES",
  :region_name    => "CALIFORNIA",
  :city           => "MONTEREY PARK",
  :zip_code       => "91754",
  :latitude       => "34.0505",
  :longitude      => "-118.13"
  :timezone       => "-08:00"
}

Obviously it is not possible to have the country precision enabled while retrieving the timezone information.

Reserved / Private / Local IPs

Passing reserved, private or local IPs, such as 127.0.0.1 will return - for all location data, for example:

GeoIpCurb.geolocation('127.0.0.1')

returns:

{
  :status_code    => "OK",
  :status_message => "",
  :ip             => "127.0.0.1",
  :country_code   => "-",
  :country_name   => "-",
  :region_name    => "-",
  :city           => "-",
  :zip_code       => "-",
  :latitude       => "0",
  :longitude      => "0"
}

Timeout

It is possible to set a timeout for all requests. By default it is one second, but you can easily set a different value. Just like you would set the api_key you can set the timeout:

GeoIp.timeout = 5 # In order to set it to five seconds

Getting it

GeoIp can be installed as a Ruby Gem:

gem install geo_ip

Rails

Bundler enabled (Rails 3.0.x and 2.3.x)

In your Gemfile:

gem 'geo_ip', '~> 0.3.0'

Then create an initializer config/initializers/geo_ip (or name it whatever you want):

GeoIp.api_key = 'YOUR_API_KEY'

Pre-bundler (Rails 2.3.x or older)

In your config/environment.rb:

config.gem 'geo_ip', :version => '~> 0.3.0'

Then create an initializer config/initializers/geo_ip (or name it whatever you want):

GeoIp.api_key = 'YOUR_API_KEY'

Testing

Set up your API key first for the test suite by creating a spec/api.yml file. Follow the example in spec/api.yml.example. Then run the tests with:

ruby spec/geo_ip_spec.rb

If you get a LoadError, you should run the tests with:

ruby -rubygems spec/geo_ip_spec.rb
