Valore della proprietà

IPAddressCollection

IPAddressCollection che contiene le informazioni di indirizzo per i server di protocollo DHCP o una matrice vuota se non vengono trovati server.

Attributi: UnsupportedOSPlatformAttribute

Esempio

Nell'esempio di codice seguente vengono visualizzate le informazioni sull'indirizzo DHCP per le interfacce di rete nel computer locale.

Commenti

Dynamic Host Configuration Protocol (DHCP) consente a un computer di ottenere un indirizzo di rete da un server DHCP, anziché usare un indirizzo di rete statico (fisso). Un server DHCP non assegna definitivamente gli indirizzi; usa invece temporaneamente uno degli indirizzi disponibili per il computer.
