Practical Subnetting

1. Analyze subnet structure, design, and limitations
2. Demonstrate practical classless subnet design
3. Define components of Subnets (Net ID, host range, Broadcast)
4. Explain the purpose and use of subnets

Given the following network constraints:

1. Design a single subnetting scheme that fits all required departments (functions) and network devices per function.
2. Be sure to allow space for future growth (in both subnets and hosts/subnet)

• Use a Class A Private IP Network

• Departments and Functions
  • Administration (78 Devices)
  • Executive (24 Devices)
  • IT (300 Devices)
  • Legal (40 Devices)
  • Accounting (60 Devices)
  • Research and Development (143 Devices)
  • Help Desk (60 Devices)
  • VoIP Infrastructure (900 Devices)
  • Printers (45 Devices)
  • Network Infrastructure (700 Devices)
  • Server Operations (300 Devices)
  • Guest Terminals (25 Devices)
  • Guest Wireless (100 Devices)
  • Help Desk Wireless (100 Devices)
  • Employee Wireless (250 Devices)
  • Maintenance (500 devices)
  • Production Floor (1,200 Devices)
  • Media (200 Devices)
  • Live Broadcast (120 Devices)
  • UPS Battery Systems (800 Devices)

The IP Network Design is entirely up to you! There are many correct answers, so be sure to explain your reasoning behind the choices you made!

Deliverables:

1. A list of each department (subnet) with the:
   1. Network ID (with CIDR)
   2. Available IPv4 addresses for use (can be multiple octets)
   3. Broadcast ID
   4. Addresses used out of total available

Example: Administration: 192.168.10.32/27 (.33 - .62)

Broadcast: 192.168.10.63 (14/30 device IPs allocated)

2. A short explanation of how and why you selected the Subnet scheme you did.
