Soal:

a.       192.168.1.100/24

b.      172.71.17.17/29

c.       202.125.100.200/26

d.      10.10.10.10/30

e.      191.168.100.160/27

f.        220.200.20.30/28

g.       180.60.50.150/25

 Jawab:

a.       192.168 .1.100/24

llllllll.llllllll.llllllll.00000000

Subnet mask      : 255.255.255.0

Network              : 192.168.1.0

Broadcast            : 192.168.1.255

NB:karena slash 24 sudah pas maka dari itu tidak perlu dihitung dan bisa di nalar.

b.      172.71.17.17/29

llllllll.llllllll.llllllll.lllll000

Subnet mask      : 255.255.255.248

Network              : 2^x = 2⁵ = 32

Host                       :2^y  = 2³ – 2 = 8 – 2 = 6

Kelipatan             : 256 – 248 = 8
