Comentarios

Esta clase proporciona acceso a la información de configuración y dirección para las interfaces de red que admiten IPv4. No se crean instancias de esta clase; se devuelven mediante el GetIPv4Properties método .

Para ver las propiedades de IPV6, vea GetIPv6Properties.

Constructores

IPv4InterfaceProperties()

Inicializa una nueva instancia de la clase IPv4InterfaceProperties.

Propiedades

Index

Obtiene el índice de la interfaz de red asociado a la dirección del Protocolo de Internet 4 (IPv4).

IsAutomaticPrivateAddressingActive

Obtiene un valor Boolean que indica si esta interfaz dispone de una dirección de direccionamiento IP privado automático (APIPA).

IsAutomaticPrivateAddressingEnabled

Obtiene un valor Boolean que indica si esta interfaz tiene habilitado el direccionamiento IP privado automático (APIPA).

IsDhcpEnabled

Obtiene un valor Boolean que indica si la interfaz se ha configurado de forma que utilice un servidor DHCP (Protocolo de configuración dinámica de host) para obtener una dirección IP.

IsForwardingEnabled

Obtiene un valor Boolean que indica si esta interfaz puede reenviar (enrutar) paquetes.

Mtu

Obtiene la unidad de transmisión máxima (MTU) para esta interfaz de red.

UsesWins

Obtiene un valor Boolean que indica si una interfaz utiliza Servicios de nombres Internet de Windows (WINS).
