Exercise 3: We want to divide 192.168.10.0 which
is class C network, into four networks, each with unequal number of IP address
requirement as shown below:
- Subnet A: 32 host.
- Subnet B: 8 host.
- Subnet C: 22 host.
- Subnet D: 60 hosts.
Solution:
Organize, high - low
·
Subnet
D: 60 hosts.
Host = 26
= 64 – 2 = 62 N = 22
= 64
·
Subnet
A: 32 host.
Host = 26
= 64 – 2 = 62 N = 22
= 64
·
Subnet
C: 22 host.
Host = 25
= 32 – 2 = 30 N = 23
= 32
·
Subnet
B: 8 host.
Host = 24
= 16 – 2 = 14 N = 24
= 16

Exercise 4: Given network of 201.4.3.0/24,
subnet the network in order to create the subnetworks with the following:
- Office 1 – 14 hosts.
- Office 2 – 60 hosts.
- Office 3 – 32 hosts.
- Office 4 – 7 hosts.
- Office 5 – 15 hosts.
Solution:
Organize, high - low
·
Office
2 – 60 hosts.
Host = 26
= 64 – 2 = 62 N = 22
= 64
·
Office
3 – 32 hosts.
Host = 26

= 64
·
Office
5 – 15 hosts.
Host = 25
= 32 – 2 = 30 N = 23
= 32
·
Office
1 – 14 hosts.
Host = 24
= 16 – 2 = 14 N = 24
= 16
·
Office
4 – 7 hosts.
Host = 24
= 16 – 2 = 14 N = 24
= 16
