Build status Code Climate

Stores the GeoIP databases in Redis and gives it a simple way to lookup IPs and map them to countries/country codes.

Get your GeoIP country CSVs from http://www.maxmind.com/app/geolite.

Trifle supports both the IPV4 and IPV6 databases.


Loading the GeoIP databases from disk is slow, and doing that for every request is a pain. Trifle keeps your GeoIP database in memory and makes it easy to query.


Install the gem

gem install trifle

or add it to your Gemfile and bundle

gem "trifle"



# Initialize
trifle = Trifle.new(Redis.new)
# Load data from file
trifle.load filename: "file.csv"
# or files
trifle.load filenames: ["file1.csv", "file2.csv"]
# or directly as an array
trifle.load data: preloaded_array

Additionally you can specify your own Redis key to store the Trifle in:

trifle = Trifle.new(Redis.new, key: "foobar")

You can also load the Trifle from the command line:

trifle redis:// file1.csv file2.csv


# Initialize
trifle = Trifle.new(Redis.new)

# Lookup for existing data
trifle.find ""
# => ["HK", "Hong Kong"]

# Lookup for missing data
trifle.find ""
# => nil
