Hitunglah jumlah Network dan Host yang akan terbentuk dari alamat IP Address dibawah ini :

1. 192.168.10.1/30
2. 172.168.10.1/16
3. 172.168.10/22
4. 10.168.5.1/8
5. 10.168.5.1/17

Netmask = 255.255.255.252

In binary = 11111111. 11111111. 11111111.11111100

Used to calculate = 11111100

Network = 2^n

= 2^6

= 64 Network

Host = 2^h-2

     = 2^2-2

     = 2 Host

2.

Netmask = 255.255.0.0

In Binary = 11111111.11111111.00000000.00000000

Used to calculate = 00000000.00000000

Network = 2^n

        = 2^0

        = 1 Network

Host    = 2^h-2

= 2^16-2

= 65534 Host

        = 64 Network

Host    = 2^h-2

= 2^10-2

= 1022 Host
