Commenti

IPv4 è un protocollo a livello di rete responsabile del routing dei pacchetti di dati dal computer di origine alla destinazione.

Per informazioni dettagliate sulle statistiche sul traffico IP disponibili per le applicazioni, vedere la documentazione della IPGlobalStatistics classe. Si noti che l'oggetto restituito da questo metodo riflette le statistiche al momento della creazione dell'oggetto IPGlobalStatistics . Queste informazioni non vengono aggiornate dinamicamente.
