Ce qui suit est une version modifiée d'un extrait que j'ai trouvé et qui utilise les éléments suivants http://ipinfodb.com/ip_locator.php pour obtenir ses informations. N'oubliez pas que vous pouvez également demander une clé API auprès d'eux et utiliser directement l'API pour obtenir les informations fournies comme bon vous semble.
