Assignment 6.1: Subnetting Enterprise - savannahc502/SavC-TechJournal-NET215 GitHub Wiki

The goal is to create a subnet table using the information below:
- Wifi Network: 1400 Nodes
- Central Office: 1100 Nodes
- East Wing: 615 Nodes
- West Wing: 550 Nodes
- Telecommuter VPN Pool: 100 Nodes
- Use 10.9.0.0/16 as the address space > 255.255.0.0 > means that the last two octets can be configured however we want.
Personal Tips:
- /24 = 255.255.255.255 = 254 usable hosts (256 total). Knowing this can help figure everything else out.
- Double check CIDR math with: https://www.freecodecamp.org/news/subnet-cheat-sheet-24-subnet-mask-30-26-27-29-and-other-ip-address-cidr-network-references/
Subnet Table:
| Subnet Name | Required Hosts | Subnet Prefix | Mask | Network Address | First Usable IP | Last Usable IP |
|---|---|---|---|---|---|---|
| WiFi Network | 1400 < 2032 | /21 | 255.255.248.0 | 10.9.0.0 | 10.9.0.1 | 10.9.7.254 |
| Central Office | 1100 < 2032 | /21 | 255.255.248.0 | 10.9.8.0 | 10.9.8.1 | 10.9.15.254 |
| East Wing | 615 < 1022 | /22 | 255.255.252.0 | 10.9.16.0 | 10.9.16.1 | 10.9.19.254 |
| West Wing | 550 < 1022 | /22 | 255.255.252.0 | 10.9.20.0 | 10.9.20.1 | 10.9.23.254 |
| VPN Pool | 100 < 126 | /25 | 255.255.255.128 | 10.9.24.0 | 10.9.24.1 | 10.9.24.126 |
