Commenti

ICMP è un set di messaggi da usare con Internet Protocol versione 4 (IPv4). ICMP viene usato dai nodi IPv4 per segnalare gli errori riscontrati nell'elaborazione dei pacchetti di dati e per eseguire altre funzioni del livello Internet. ICMP versione 4 è definito in IETF RFC 792.

Per informazioni dettagliate sulle statistiche del traffico ICMP versione 4 disponibili per le applicazioni, vedere la documentazione della IcmpV4Statistics classe. Si noti che il IcmpV4Statistics oggetto restituito da questo metodo riflette le statistiche al momento della creazione dell'oggetto. Queste informazioni non vengono aggiornate dinamicamente.
