To get ip2location data, you need to download csv file DB3.LITE (it's free) from here (http://lite.ip2location.com/).

Then you need to run a sql query for loading data from csv in table. Here is the query:

  LOAD DATA LOCAL INFILE '/path/to/file.csv' INTO TABLE oggetto_geodetection_iplocations 
  FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' 
  (ip_from, ip_to, country_code, country_name, region_name, city_name);

It can throw few errors or exceptions. To fix them you need to do 1,2,6,7 items in this insruction list. Also you need to run your mysql with this parameter: --local-infile

    mysql -uuser -ppassword --local-infile
