Uwagi

IPv4 to protokół warstwy sieciowej, który jest odpowiedzialny za routing pakietów danych z komputera źródłowego do miejsca docelowego.

Aby uzyskać szczegółowe informacje na temat statystyk ruchu IP dostępnych dla aplikacji, zobacz dokumentację IPGlobalStatistics klasy. Należy pamiętać, że obiekt zwrócony przez tę metodę odzwierciedla statystyki od czasu utworzenia IPGlobalStatistics obiektu. Te informacje nie są aktualizowane dynamicznie.
