Subnetting Challenge: The Network Storm
Calculate subnets for a disaster recovery scenario with strict IP requirements.
Overview
Challenge Type: IP Subnetting & Network Planning
You've been tasked with configuring networks for a new remote office expansion. The main network 192.168.0.0/24 must be divided among three departments with the following requirements:

- Human Resources: 30 host addresses
- Executive Offices: 12 host addresses
Task:
Determine the optimal subnetting plan that meets these requirements while minimizing address waste. Also account for potential future expansion of 30% in each department.

Step 1:
Calculate each department's host requirement with 30% buffer.
IT: 50+15=65, HR: 30+9=39, Exec: 12+4=16
Step 2:
Determine the largest required subnet size first (64 hosts)
Use /26 for largest, then /27, then /28 for remaining
