Paper For Above Instructions

Subnetting is a crucial aspect of network design that allows for efficient IP address management by dividing a larger network into smaller, manageable sub-networks or subnets. This paper focuses on subnetting the IP address 192.168.1.0 to accommodate specific device and network requirements. The main goals are to create subnets that host 15 devices each, including the router gateway interface, and to further divide the 192.168.1.0 network into 25 subnets.

Subnetting to Accommodate 15 Devices

When subnetting a network to support a certain number of devices, it’s important to consider the total number of usable IP addresses required. Each subnet must accommodate the devices plus the network address and the broadcast address. In this case, for 15 devices, we will need a subnet that provides at least 17 IP addresses (15 hosts + 1 network + 1 broadcast).

The formula to calculate the number of hosts that can fit into a subnet is given by:

Usable Hosts = 2^n - 2

where n represents the number of bits left for hosts. To determine the appropriate subnet mask, we need to find the smallest 'n' such that:

2n - 2 ≥ 17

Testing small values of n:

  • If n = 5: 25 - 2 = 30 (sufficient)

  • If n = 4: 24 - 2 = 14 (not sufficient)

This shows that we need to reserve 5 bits for host addressing, meaning the subnet mask will be:

Subnet Mask: 255.255.255.224 (or /27)

This subnet mask allows for 32 addresses in total (0-31), which gives us 30 usable addresses.

Calculating Subnets and Their Details

Given the subnet mask of /27 (255.255.255.224), we will subnet the network 192.168.1.0. The range of IP addresses for the first subnet will be:

  • Subnet ID (Network IP): 192.168.1.0

  • Host Range IPs: 192.168.1.1 - 192.168.1.30

  • Broadcast IP: 192.168.1.31

For multiple subnets, here are the first five created by continuing to step through the increment of 32 addresses:

  1. Subnet 1:

    • Subnet ID: 192.168.1.0

    • Host Range: 192.168.1.1 - 192.168.1.30

    • Broadcast: 192.168.1.31

    • Subnet Mask: 255.255.255.224

  2. Subnet 2:

    • Subnet ID: 192.168.1.32

    • Host Range: 192.168.1.33 - 192.168.1.62

    • Broadcast: 192.168.1.63

    • Subnet Mask: 255.255.255.224

  3. Subnet 3:

    • Subnet ID: 192.168.1.64

    • Host Range: 192.168.1.65 - 192.168.1.94

    • Broadcast: 192.168.1.95

    • Subnet Mask: 255.255.255.224

  4. Subnet 4:

    • Subnet ID: 192.168.1.96

    • Host Range: 192.168.1.97 - 192.168.1.126

    • Broadcast: 192.168.1.127

    • Subnet Mask: 255.255.255.224

  5. Subnet 5:

    • Subnet ID: 192.168.1.128

    • Host Range: 192.168.1.129 - 192.168.1.158

    • Broadcast: 192.168.1.159

    • Subnet Mask: 255.255.255.224

Subnetting to Accommodate 25 Networks

In order to create 25 subnets from the 192.168.1.0 network, we again apply the formula for calculating the number of possible subnets:

Subnets = 2^n

To accommodate 25 networks:

2n ≥ 25

Testing small values of n:

  • If n = 5: 25 = 32 (sufficient)

  • If n = 4: 24 = 16 (not sufficient)

Thus, we need 5 bits for subnetting, which means we will use a subnet mask of:

Subnet Mask: 255.255.255.224 (or /27)

Each of the 25 required subnets is already established with the previously filled addresses. Here is a brief summary of these additional 25 subnets, keeping the increments consistent:

  • First five subnets (as previously listed) cover Subnet IDs 192.168.1.0, 192.168.1.32, 192.168.1.64, 192.168.1.96, 192.168.1.128.

  • Continuing further would produce additional subnet IDs up to 192.168.1.224, thus accommodating the necessary 25 networks.

In conclusion, utilizing subnetting efficiently provides a more optimal approach to managing IP addresses for network structures. The practical application of subnetting assists in maximizing the available addresses while ensuring that each device has a unique and reachable IP address within their respective subnets.
