Usage

db = MaxMindDB.new('./GeoLite2-City.mmdb')
ret = db.lookup('74.125.225.224')

ret.found? # => true
ret.country.name # => 'United States'
ret.country.name('zh-CN') # => '美国'
ret.country.iso_code # => 'US'
ret.city.name(:fr) # => 'Mountain View'
ret.location.latitude # => -122.0574
ret.to_hash # => {"city"=>{"geoname_id"=>5375480, "names"=>{"de"=>"Mountain View", "en"=>"Mountain View", "fr"=>"Mountain View", "ja"=>"マウンテンビュー", "ru"=>"Маунтин-Вью", "zh-CN"=>"芒廷维尤"}}, "continent"=>{"code"=>"NA", "geoname_id"=>6255149, "names"=>{"de"=>"Nordamerika", "en"=>"North America", "es"=>"Norteamérica", "fr"=>"Amérique du Nord", "ja"=>"北アメリカ", "pt-BR"=>"América do Norte", "ru"=>"Северная Америка", "zh-CN"=>"北美洲"}}, "country"=>{"geoname_id"=>6252001, "iso_code"=>"US", "names"=>{"de"=>"USA", "en"=>"United States", "es"=>"Estados Unidos", "fr"=>"États-Unis", "ja"=>"アメリカ合衆国", "pt-BR"=>"Estados Unidos", "ru"=>"Сша", "zh-CN"=>"美国"}}, "location"=>{"latitude"=>37.419200000000004, "longitude"=>-122.0574, "metro_code"=>807, "time_zone"=>"America/Los_Angeles"}, "postal"=>{"code"=>"94043"}, "registered_country"=>{"geoname_id"=>6252001, "iso_code"=>"US", "names"=>{"de"=>"USA", "en"=>"United States", "es"=>"Estados Unidos", "fr"=>"États-Unis", "ja"=>"アメリカ合衆国", "pt-BR"=>"Estados Unidos", "ru"=>"Сша", "zh-CN"=>"美国"}}, "subdivisions"=>[{"geoname_id"=>5332921, "iso_code"=>"CA", "names"=>{"de"=>"Kalifornien", "en"=>"California", "es"=>"California", "fr"=>"Californie", "ja"=>"カリフォルニア州", "pt-BR"=>"Califórnia", "ru"=>"Калифорния", "zh-CN"=>"加利福尼亚州"}}]}

Even if no result could be found, you can ask for the attributes without guarding for nil:

db = MaxMindDB.new('./GeoLite2-City.mmdb')
ret = db.lookup('127.0.0.1')
ret.found? # => false
ret.country.name # => nil
ret.to_hash # => {}
