Question

In: Computer Science

You have network address as 192.1.1.0/24. Subnet it into /27 network.

Expert Solution

According to the question, the network address is 192.1.1.0/24 where 24 represents the network ID, now we have to subnet it into /27 networks. the difference between NID's in subnet and network is 3 (27-24) which means the network will be divided into 2³ or 8 subnets.

Address: 192.1.1.0
Binary representation: 11000000.00000001.00000001.00000000

Netmask: 255.255.255.0 = 24
Binary representation: 11111111.11111111.11111111.00000000

Network: 192.1.1.0/24
Binary representation: 11000000.00000001.00000001.00000000 (Class C)

Broadcast: 192.1.1.255
Binary representation: 11000000.00000001.00000001.11111111

HostMin: 192.1.1.1
Binary representation: 11000000.00000001.00000001.00000001

HostMax: 192.1.1.254
Binary representation: 11000000.00000001.00000001.11111110

Hosts/nets: 254
Since network is divided into 8 subnets therefore each subnets has 256/8 =32 hosts.
here 256 includes 254 hosts, 1 network(when all HID=0) and 1 directed broadcast address (when all HID =1)

The 8 subnets are as follows:-

Subnet 1:-

Network: 192.1.1.0/27 (Class C)
Broadcast: 192.1.1.31
HostMin: 192.1.1.1
HostMax: 192.1.1.30
Hosts/nets: 30

Subnet 2:-

Network: 192.1.1.32/27 (Class C)
Broadcast: 192.1.1.63
HostMin: 192.1.1.33
HostMax: 192.1.1.62
Hosts/nets: 30

Subnet 3:-

Network: 192.1.1.64/27 (Class C)
Broadcast: 192.1.1.95
HostMin: 192.1.1.65
HostMax: 192.1.1.94
Hosts/nets: 30

Subnet 4:-

Network: 192.1.1.96/27 (Class C)
Broadcast: 192.1.1.127
HostMin: 192.1.1.97
HostMax: 192.1.1.126
Hosts/nets: 30

Subnet 5:-

Network: 192.1.1.128/27 (Class C)
Broadcast: 192.1.1.159
HostMin: 192.1.1.129
HostMax: 192.1.1.158
Hosts/nets: 30

Subnet 6:-

Network: 192.1.1.160/27 (Class C)
Broadcast: 192.1.1.191
HostMin: 192.1.1.161
HostMax: 192.1.1.190
Hosts/nets: 30

Subnet 7:-

Network: 192.1.1.192/27 (Class C)
Broadcast: 192.1.1.223
HostMin: 192.1.1.193
HostMax: 192.1.1.222
Hosts/nets: 30

Subnet 8:-

Network: 192.1.1.224/27 (Class C)
Broadcast: 192.1.1.255
HostMin: 192.1.1.225
HostMax: 192.1.1.254
Hosts/nets: 30
