Exercise Subnetting

1. 

Given the Class C network of 204.15.5.0/24, subnet the network in order to create the network in Figure 3 with the host requirements shown.

Jawab:

Tanpa VLSM
Jumlah host terbesar = 28 hosts = 5 bit (karena 2^5 = 32)
Jumlah subnet = 5 = 3 bit (karena 2^3 = 8)
5 bit + 3 bit = 8 bit ---> cocok

Subnet Mask yang akan dipakai (natural mask diperluas 3 bit) = 255.255.255.(128+64+32)
= 255.255.255.224 atau /27

netA: 204.15.5.0 /27
netB: 204.15.5.32/27
netC: 204.15.5.64/27
netD: 204.15.5.96/27
netE: 204.15.5.128/27


Dengan VLSM

netB: 204.15.5.0 255.255.255.224
netE: 204.15.5.32 255.255.255.224
netA: 204.15.5.64 255.255.255.240
netD: 204.15.5.80 255.255.255.240
netC: 204.15.5.96 255.255.255.252
