Question

One day your supervisor walks to you, saying: "here is the network ID 192.168.0.0/24, please create three separate networks or subnets for a coffee shop: Sunny Cafe." The three separate subnets/networks are: One is for the office, one for the front desk and storage room, and one is for public use.

Required:
Your task is to list each subnet, network ID, subnet mask, Host ID Range, # of usable host IDs, and Broadcast ID

Answer 1

See the explanation for the answer

Step-by-step explanation:

Given, network address is: 192.168.0.0/24

The requirement is to create 3 subnets from this network.

3 is near to 4 in powers of 2 => 22

We need 2 bits for subnetting.

So, total number of network bits are: 24 + 2 = 26 bits

Number of host bits are: 32 - 26 = 6 bits [since total number of bits in a address is 32]

Total number of hosts in a subnet: 26 = 64 hosts

Total number of valid hosts: 64 - 2 = 62 hosts [2 => 1 is for network address and 1 is subnet mask]

Subnet Network ID Subnet Mask

1 192.168.0.0/26 255.255.255.192

2 192.168.0.64/26 255.255.255.192

3 192.168.0.128/26 255.255.255.192

4 192.168.0.192/26 255.255.255.192

Subnet Host ID range #of usable host IDs Broadcast ID

1 192.168.0.1 - 62 192.168.0.63

192.168.0.62

2 192.168.0.65 - 62 192.168.0.127

192.168.0.126

3 192.168.0.129 - 62 192.168.0.191

192.168.0.190

4 192.168.0.193 - 62 192.168.0.255

192.168.0.254
