Beispiele

Im folgenden Codebeispiel werden die DHCP-Adressinformationen für die Netzwerkschnittstellen auf dem lokalen Computer angezeigt.

Hinweise

Dhcp (Dynamic Host Configuration Protocol) ermöglicht es einem Computer, eine Netzwerkadresse von einem DHCP-Server abzurufen, anstatt eine statische (feste) Netzwerkadresse zu verwenden. Ein DHCP-Server weist keine dauerhaften Adressen zu. stattdessen wird vorübergehend eine von mehreren verfügbaren Adressen für den Computer verwendet.
