Why use subnetting?

Illustrate having 30 hosts. Using a Class C network the waste of IP is great (254-30=224 wasted IP addresses).

Furthermore we create smaller broadcast domains resulting to reduced network traffic and simplify fault troubleshooting by isolating network problems down to their specific existence.
