Contoh
Contoh kode berikut mendapatkan GetIPv4Properties objek dan menampilkan datanya.
void DisplayIPv4NetworkInterfaces()

Keterangan
Kelas ini menyediakan akses ke informasi konfigurasi dan alamat untuk antarmuka jaringan yang mendukung IPv4. Anda tidak membuat instans kelas ini; mereka dikembalikan oleh GetIPv4Properties metode .
Untuk properti IPV6, lihat GetIPv6Properties.
Konstruktor
IPv4InterfaceProperties() |
Menginisialisasi instans baru kelas IPv4InterfaceProperties. |
Properti
Index |
Mendapatkan indeks antarmuka jaringan yang terkait dengan alamat Protokol Internet versi 4 (IPv4). |
IsAutomaticPrivateAddressingActive |
Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka ini memiliki alamat ALAMAT IP privat otomatis (APIPA). |
IsAutomaticPrivateAddressingEnabled |
Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka ini mengaktifkan alamat IP privat otomatis (APIPA). |
IsDhcpEnabled |
Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka dikonfigurasi untuk menggunakan server Dynamic Host Configuration Protocol (DHCP) untuk mendapatkan alamat IP. |
IsForwardingEnabled |
Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka ini dapat meneruskan (merutekan) paket. |
Mtu |
