Remarques

IPv4 est un protocole de couche réseau qui est responsable du routage des paquets de données de son ordinateur source vers sa destination.

Pour plus d’informations sur les statistiques de trafic IP disponibles pour les applications, consultez la documentation de la IPGlobalStatistics classe. Notez que l’objet retourné par cette méthode reflète les statistiques au moment de la création de l’objet IPGlobalStatistics . Ces informations ne sont pas mises à jour dynamiquement.
