Hinweise

Diese Klasse stellt den Zugriff auf Konfigurations- und Adressinformationen für Netzwerkschnittstellen, IPv4 unterstützen.This class provides access to configuration and address information for network interfaces that support IPv4. Erstellen Sie Instanzen dieser Klasse nicht. Diese zurückgegeben werden, indem die GetIPv4Properties Methode.You do not create instances of this class; they are returned by the GetIPv4Properties method.

IPv6-Eigenschaften finden Sie unter GetIPv6Properties.For IPV6 properties, see GetIPv6Properties.
