Example 4: Classless Inter-Domain Routing (CIDR) (Super-netting)

Question:

IP - 192.168.1.0 / 24

Need 3 Subnet with Each 50 Hosts?

Answer:

Result Imagination Diagram

Already Class C Given.So we will Calculate host using class C

Calculating Host's

So 6 bit's is enough to get 50 hosts

Sub-netting

1^st Subnet: (Vlan 1)

1st Subnet

Network ID            : 192.168.1.64

1^st Host ID             : 192,168.1.65

Last Host ID            : 192.168.1.126

Broadcast ID           : 192.168.1.127

Subnet Mask               : 255.255.255.192

2^nd Subnet (Vlan 2)

2nd Subnet

Network ID            : 192.168.1.128

1^st Host ID             : 192.168.1.129

Last Host ID          : 192.168.1.190

Broadcast ID         : 192.168.1.191

Subnet Mask             : 255.255.255.192

3^rd Subnet (Vlan 3)

3^rd Subnet

Network ID            : 192.168.1.192

1^st Host ID             : 192.168.1.193

Last Host ID          : 192.168.1.254

Broadcast ID         : 192.168.1.255

Subnet Mask             : 255.255.255.192
