This is the official Ruby client library for the IPinfo.io IP address API, allowing you to lookup your own IP address, or get any of the following details for an IP:

• IP geolocation data (city, region, country, postal code, latitude and longitude)
• ASN information (ISP or network operator, associated domain name, and type, such as business, hosting or company)
• Firmographic data (the name and domain of the business that uses the IP address)
• Carrier details (the name of the mobile carrier and MNC and MCC for that carrier if the IP is used exclusively for mobile traffic)

Check all the data we have for your IP address here.

You'll need an IPinfo API access token, which you can get by singing up for a free account at https://ipinfo.io/signup.

The free plan is limited to 50,000 requests per month, and doesn't include some of the data fields such as IP type and company data. To enable all the data fields and additional request volumes see https://ipinfo.io/pricing

Add this line to your application's Gemfile:

gem 'IPinfo'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install IPinfo

require 'ipinfo'

access_token = '123456789abc'
handler = IPinfo::create(access_token)
ip_address = '216.239.36.21'

details = handler.details(ip_address)
city = details.city # Emeryville
loc = details.loc # 37.8342,-122.2900

If using this in package in Rails 6 , the zeitwerk auto-loader may not properly recognize the gem due to its naming conventions (uppercased gem/module name). See issue ipinfo#24.

A workaround is to insert this in application.rb:

require 'ipinfo' unless defined?(IPinfo)

The IPinfo.details() method accepts an IP address as an optional, positional argument. If no IP address is specified, the API will return data for the IP address from which it receives the request.

require 'ipinfo'

access_token = '123456789abc'
handler = IPinfo::create(access_token)

details = handler.details()
city = details.city # "Emeryville"
loc = details.loc # 37.8342,-122.2900

The IPinfo library can be authenticated with your IPinfo API token, which is passed in as a positional argument. It also works without an authentication token, but in a more limited capacity.

access_token = '123456789abc'
handler = IPinfo::create(access_token)

handler.details() will return a Response object that contains all fields listed in the IPinfo developerdocs with a few minor additions. Properties can be accessed directly.

hostname = details.hostname # cpe-104-175-221-247.socal.res.rr.com

details.country_name will return the country name, as supplied by the countries.json file. See below for instructions on changing that file for use with non-English languages. details.country will still return country code.

country = details.country # US
country_name = details.country_name # United States

details.is_eu will return true if the country is a member of the European Union (EU), as supplied by the eu.json file.

is_eu = details.is_eu # false

It is possible to change the file by setting the eu_countries setting when creating the IPinfo object.

The file must be a .json file with the following structure.

details.country_flag will return emoji and unicode of a country's flag, as supplied by the eu.json file.

country_flag = details.country_flag # {"emoji"=>"🇺🇸", "unicode"=>"U 1F1FA U 1F1F8"}
country_flag_emoji = details.country_flag['emoji'] # 🇺🇸
country_flag_unicode = details.country_flag['unicode'] # U 1F1FA U 1F1F8

details.country_flag_url will return a public link to the country's flag image as an SVG which can be used anywhere.

country_flag = details.country_flag_url # {"https://cdn.ipinfo.io/static/images/countries-flags/US.svg"}

details.country_currency will return code and symbol of a county's currency, as supplied by the currency.json file.

country_currency = details.country_currency # {"code"=>"USD", "symbol"=>"$"}
country_currency_code = details.country_currency['code'] # USD
country_currency_symbol = details.country_currency['symbol'] # $

It is possible to change the file by setting the countries_currencies setting when creating the IPinfo object.

The file must be a .json file with the following structure.

details.continent will return code and name of the continent, as supplied by the continent.json file.

continent = details.continent # {"code"=>"NA", "name"=>"North America"}
continent_code = details.continent['code'] # NA
continent_name = details.continent['name'] # North America

It is possible to change the file by setting the continets setting when creating the IPinfo object.

The file must be a .json file with the following structure.

details.ip_address will return the an IPAddr object from the Ruby Standard Library. details.ip will still return a string.

ip = details.ip # 104.175.221.247
ip_addr = details.ip_address # <IPAddr: IPv4:104.175.221.247/255.255.255.255>

details.latitude and details.longitude will return latitude and longitude, respectively, as strings. details.loc will still return a composite string of both values.

loc = details.loc # 34.0293,-118.3570
lat = details.latitude # 34.0293
lon = details.longitude # -118.3570

details.all will return all details data as a dictionary.

details.all = {
:asn => {  :asn => 'AS20001',
           :domain => 'twcable.com',
           :name => 'Time Warner Cable Internet LLC',
           :route => '104.172.0.0/14',
           :type => 'isp'},
:city => 'Los Angeles',
:company => {  :domain => 'twcable.com',
               :name => 'Time Warner Cable Internet LLC',
               :type => 'isp'},
:country => 'US',
:country_name => 'United States',
:hostname => 'cpe-104-175-221-247.socal.res.rr.com',
:ip => '104.175.221.247',
:ip_address => <IPAddr: IPv4:104.175.221.247/255.255.255.255>,
:loc => '34.0293,-118.3570',
:latitude => '34.0293',
:longitude => '-118.3570',
:phone => '323',
:postal => '90016',
:region => 'California'
}

In-memory caching of details data is provided by default via the lru_redux gem. This uses an LRU (least recently used) cache with a TTL (time to live) by default. This means that values will be cached for the specified duration; if the cache's max size is reached, cache values will be invalidated as necessary, starting with the oldest cached value.

Cache behavior can be modified by setting the cache_options keyword argument. cache_options is a dictionary in which the keys are keyword arguments specified in the cachetools library. The nesting of keyword arguments is to prevent name collisions between this library and its dependencies.

• Default maximum cache size: 4096 (multiples of 2 are recommended to increase efficiency)
• Default TTL: 24 hours (in seconds)

token = '1234'
handler = IPinfo::create(token, {:ttl => 30, :maxsize => 30})

It's possible to use a custom cache by creating a child class of the CacheInterface class and passing this into the handler object with the cache keyword argument. FYI this is known as the Strategy Pattern.

handler = IPinfo.handler(token, {:cache => my_fancy_custom_class})

Ruby is notorious for having lots of HTTP libraries. While Net::HTTP is a reasonable default, you can set any other that Faradaysupports if you prefer.

access_token = '123456789abc'
handler = IPinfo::create(access_token, {:http_client => my_client})

Don't forget to bundle the custom HTTP library as well.

When looking up an IP address, the response object includes a details.country_name attribute which includes the country name based on American English. It is possible to return the country name in other languages by setting the countries setting when creating the IPinfo object.

The file must be a .json file with the following structure:

{
 "BD": "Bangladesh",
 "BE": "Belgium",
 "BF": "Burkina Faso",
 "BG": "Bulgaria"
 ...
}
