Poznámky

ICMP je sada zpráv pro použití s protokolem IPv4 (Internet Protocol verze 4). Protokol ICMP používají uzly protokolu IPv4 k hlášení chyb při zpracování datových paketů a k provádění dalších funkcí internetové vrstvy. ICMP verze 4 je definován v IETF RFC 792.

Podrobnosti o statistikách provozu PROTOKOLU ICMP verze 4, které jsou k dispozici pro aplikace, najdete v dokumentaci ke IcmpV4Statistics třídě. Všimněte si IcmpV4Statistics , že objekt vrácený touto metodou odráží statistiky k okamžiku vytvoření objektu. Tyto informace se neaktualizují dynamicky.
