IPLookup

IPLookup uses GeoIP2 MaxMind DB to lookup the country, timezone, coordinates and subdivision for a given ip address.

Dependencies

• Uses the gem maxminddb as a database reader.
• Uses the gem TZInfo for timezone lookup.
• Uses the gem Zlib to decompress database file.

Installation

Add this line to your application's Gemfile:

gem 'ip_lookup'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ip_lookup

Configuration

Before using the gem the db file needs to be downloaded / updated.

# download / update database
IPLookup.DB.update update_period: 30, update_uri: "http://path_to_database_GeoLite2-City.mmdb.gz"

• default update_period (in days): 30
