  The first argument is the filename of the GeoIPCity.dat file load_option = :standard, :index, or :memory.

Instance Method Summary

• #look_up(addr) ⇒ Object

  Pass this function an IP address as a string, it will return a hash containing all the information that the database knows about the IP db.look_up(‘24.24.24.24’) => :latitude=>42.4277992248535, :country_code=>“US”, :longitude=>-76.4981994628906, :country_code3=>“USA”, :dma_code=>555, :country_name=>“United States”, :area_code=>607, :region=>“NY”.

Class Method Details

.new(*args) ⇒ Object

The first argument is the filename of the GeoIPCity.dat file load_option = :standard, :index, or :memory. default :memory check_cache = true or false. default false

filesystem: read database from filesystem, uses least memory.

index: the most frequently accessed index portion of the database,

resulting in faster lookups than :filesystem, but less memory usage than
:memory.

memory: load database into memory, faster performance but uses more

memory.
