The slides will practically guide you through the steps of class B IP address subnetting. The generation of Network IP, the subnet mask, the broadcast IP are also generated.

1. CLASS B
SUBNETTING

2. IP address = 172.168.0.0 / 19
Subnet mask = 11111111.11111111.11100000.00000000
= 255.255.224.0
No. of Hosts per Network = 213 - 2 = 8192 – 2 = 8190
Block size = 256 – 224 = 32
No. of Networks = 23 = 8

3. 1st Network:
1st Network ID = 172.168.0.0
1st Valid IP address = 172.168.0.1
Last Valid IP address = 172.168.31.254
Broadcast IP address = 172.168.31.255
2nd Network:
2nd Network ID = 172.168.32.0
1st Valid IP address = 172.168.32.1
Last Valid IP address = 172.168.63.254
Broadcast IP address = 172.168.63.255

4. 3rd Network:
3rd Network ID = 172.168.64.0
1st Valid IP address = 172.168.64.1
Last Valid IP address = 172.168.95.254
Broadcast IP address = 172.168.95.255
4th Network:
4th Network ID = 172.168.96.0
1st Valid IP address = 172.168.96.1
Last Valid IP address = 172.168.127.254
Broadcast IP address = 172.168.127.255

5. 5th Network:
5th Network ID = 172.168.128.0
1st Valid IP address = 172.168.128.1
Last Valid IP address = 172.168.159.254
Broadcast IP address = 172.168.159.255
6th Network:
6th Network ID = 172.168.160.0
1st Valid IP address = 172.168.160.1
Last Valid IP address = 172.168.191.254
Broadcast IP address = 172.168.191.255

6. 7th Network:
7th Network ID = 172.168.192.0
1st Valid IP address = 172.168.192.1
Last Valid IP address = 172.168.223.254
Broadcast IP address = 172.168.223.255
8th Network:
8th Network ID = 172.168.224.0
1st Valid IP address = 172.168.224.1
Last Valid IP address = 172.168.255.254
Broadcast IP address = 172.168.255.255
