§  IP address classes and Subnetting 

Question No.1:

Following diagram has four subnets of different IP classes that are connected via WAN link. You are required to find maximum number of useable host that each subnet can accommodate. Write your answer in given table:

Subnet address	Maximum useable hosts
192.168.0.0/29
192.168.1.0/26
172.16.1.28/20
10.0.0.0/13

Question – 2

Suppose a university has a class C network 198.1.1.0 and wants to form subnets for its five departments, with hosts as follows:

Departments	Required No. of hosts
Math	60
Computer science	80
Management	55
Finance	35
HR	4

You are required to give a possible arrangement of Subnet Prefix/ CIDR to make this possible in following table:

IP address	Departments	Required No. of Hosts	Subnet Prefix/ CIDR
198.1.1.0	Math	60
198.1.1.0	Computer science	80
198.1.1.0	Management	45
198.1.1.0	Finance	28
198.1.1.0	HR	4

Note: CIDR notation/CIDR length must be in format ‘/network bits’ for example /24

Solution:1:

Subnet address	Maximum useable hosts
192.168.0.0/29	6
192.168.1.0/26	62
172.16.1.28/20	4094
10.0.0.0/13	524286

Solution No.2:

IP address	Departments	Required No. of Hosts	Subnet Prefix/ CIDR
198.1.1.0	Math	60	255.255.255.192/26
198.1.1.0	Computer science	80	255.255.255.128/25
198.1.1.0	Management	45	255.255.255.192/26
198.1.1.0	Finance	28	255.255.255.224/27
198.1.1.0	HR	4	255.255.255.248/29
