Cari bilangan host dan bilangan network bagi yang berikut.

1) 10 . 0 . 0 . 0 / 15
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 255 . 0 . 0 . 0
1111 1111 . 1111 1110 . 0000 0000 . 0000 0000
= 2^17
= 131072 - 2
= 131070
ii) Bilangan Network = 2^7
= 128

2) 128 . 3 . 0 . 0 / 30
30 = 1111 1100
i) Bilangan Host = 2^2 ii) Bilangan Network = 2^6
= 4 - 2 = 64
= 2

3) 192 . 168 . 1 . 0 / 27
27 = 1110 0000
i) Bilangan Host = 2^5 ii) Bilangan Network = 2^3
= 32 - 2 = 8
= 30

4) 11 . 0 . 0 . 0 / 12
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 2^20 ii) Bilangan Network = 2^4
= 1048576 - 2 = 16
= 1048574

5) 13 . 0 . 0 . 0 / 30
i) Bilangan Host = 2^2 ii) Bilangan Network = 2^6
= 4 - 2 = 64
= 2

6) 130 . 11 . 0 . 0 / 22
Class B = 255 . 255 . 0 . 0
i) Bilangan Host = 2^10 ii) Bilangan Network = 2^6
= 1024 - 2 = 64
= 1022

7) 132 . 9 . 0 . 0 / 18
Class B = 255 . 255 . 0 . 0
i) Bilangan Host = 2^14 ii) Bilangan Network = 2^2
= 16384 - 2 = 4
= 16382

8) 6 . 0 . 0 . 0 / 9
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 2^23 ii) Bilangan Network = 2^1
= 8388608 - 2 = 2
= 8388606
