Diketahui sebuah network 192.168.1.0/31. Hitunglah jumlah subnet, jumlah host per subnet, blok subnet dan alamat host dan broadcast yang benar !

Subnet Mask: 255.255.255.254
Binary Subnet Mask: 11111111.11111111.11111111.11111110

  1. Jumlah Subnet = 2x ,dimana x adalah banyaknya binary 1 pada octet terkhir subnetmask (2 oktet terakhir untuk kelas B, dan 3 oktet terakhir untuk kelas A). Jadi  jumlah subnet adalah 27 = 128 subnet.
  2. Jumlah Host per Subnet = 2y – 2 ,dimana y adalah kebalikan dari x yaitu banyaknya binary 0 pada octet terakhir subnet. Jadi jumlah host per subnet adalah 21 – 2 = 0 host.
  3. Blok Subnet = 256 – 254 (nilai octet terakhir subnetmask) = 2. Subnet berikutnya adalah 2+2=4, 4+2=6, 6+2 =8, 8+2=10, 10+2 = 12 sampai dengan 248+2=250, 250+2 =252, 252+2=254 . Jadi subnet lengkapnya adalah 0,2,4,6,8,10,12 …..,250,252,254.
  4. Alamat host dan broadcast yang valid :
