Part 3 Subnetting IPv4 (Three Problem)

Before Action I perform has 3 main problem:
1- Spoiled IP:
– It means in every network of Class we have 254 host .
– Now for every department I use only 20 host ( 1-20 ) and 234 IP address are spoiled.
– And totally in 5 Department I spoiled 1170 IP address
2- Step Down Bandwidth:
– It means when host 192.168.1.1 ping 192.168.1.20 now Switch generate – broadcast for 254 host.
– And this action will be incase of Step Down Bandwidth ( internet speed )
3- Security Risk:
– Before I said when I used 192.168.1.1 – 192.168.1.20 it’s ok but now from 21 – 254 IP Address are not assigned.
– Now everyone can assign this IP for his PC and can comfortable can Ping PC of our Department.
