Comment géolocaliser une adresse IP ?
Comment savoir de quel pays provient tel utilisateur ?

Voici un code qui vous permettra de créer une base de données SQLite, et vous permettra ainsi de répondre aux questions précédentes.

Procédure :

  • Récupérer le zip suivant : http://www.blogama.org/ipinfodb_csv.zip
  • Le décompresser dans un dossier et mettre les CSV dans un même dossier
  • Utiliser le code suivant pour créer la base de données SQLite (Attention : le processus du code peut durer environ 1h30)
