Jawab:

1. 172.20.0.0/20
255.255.240.0

x y
Jumlah Subnet = 24 = 16
Jumlah Host = 212 – 2 = 4094
Jumlah Blok Subnet = 256 – 240 = 16


1 = 0
2 = 0 + 16 = 16
3 = 16 + 16 = 32
4 = 32 + 16 = 48
5 = 48 + 16 = 64
6 = 64 + 16 = 80
7 = 80 + 16 = 96
8 = 96 + 16 = 112
9 = 112 + 16 = 128
10 = 128 + 16 = 144
11 = 144 + 16 = 160
12 = 160 + 16 = 176
13 = 176 + 16 = 192
14 = 192 + 16 = 208
15 = 208 + 16 = 224
16 = 224 + 16 = 240
