The Cto Appreciated The Analysis Performed Between The Cloud Service P

The CTO appreciated the analysis performed between the cloud service providers (Amazon, Google, and Microsoft). She has decided to proceed with an Amazon Virtual Private Cloud. Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you've defined. This virtual network closely resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of AWS. To begin, the CEO would like you to provision two subnets. One subnet will be for the developers (Subnet A), which will be provisioned with 146.38.70.105/20. The second subnet will be for the marketing department (Subnet B), which will be provisioned with 215.16.52.119/19. 2. What is the network address, broadcast address, and subnet mask for Subnet A and B? Perform the necessary calculations and explain your answer.

Introduction

The selection and configuration of subnets within a Virtual Private Cloud (VPC) are crucial for effective network management and security. Proper understanding of subnetting, including calculating network addresses, broadcast addresses, and subnet masks, ensures efficient utilization of IP address space and facilitates segmentation of network resources. In this paper, we analyze two specific subnets designated for different departments, Calculate their network and broadcast addresses, and determine their subnet masks based on the given IP addresses and CIDR notations.

Understanding Subnetting Basics

Subnetting involves dividing an IP network into multiple smaller networks, or subnets, which allows better management, security, and segmentation. Key concepts in subnetting include the network address, broadcast address, and subnet mask. The network address identifies the subnet itself, the broadcast address is used to send data to all hosts within a subnet, and the subnet mask delineates the boundary between the network and host portions of the IP address (Frisch, 2019).

Calculating Subnet Details for Subnet A

Subnet A uses the IP address 146.38.70.105 with a /20 CIDR notation. The /20 indicates the first 20 bits are allocated to the network portion, leaving 12 bits for host addresses (since IPv4 addresses are 32 bits in total).

Step 1: Convert the IP address to binary

146.38.70.105 in binary:

- 146: 10010010

- 38: 00100110

- 70: 01000110

- 105: 01101001

Step 2: Determine the subnet mask

A /20 prefix corresponds to:

- 255.255.240.0, or in binary:

11111111.11111111.11110000.00000000

Step 3: Calculate the network address

Applying the subnet mask:

- IP: 10010010.00100110.01000110.01101001

- Mask: 11111111.11111111.11110000.00000000

Performing an AND operation:

- Network address: 10010010.00100110.01000000.00000000, which translates back to decimal as 146.38.64.0

Step 4: Determine the broadcast address

Set all host bits to 1:

- Host bits: last 12 bits of the address

- Network bits fixed, host bits all 1s:

10010010.00100110.01001111.11111111

- Which computes to: 146.38.79.255

Result for Subnet A:

- Network address: 146.38.64.0

- Broadcast address: 146.38.79.255

- Subnet mask: 255.255.240.0

Calculating Subnet Details for Subnet B

Subnet B uses IP address 215.16.52.119 with a /19 CIDR notation. The /19 indicates the first 19 bits are dedicated to the network.

Step 1: Convert the IP address to binary

- 215: 11010111

- 16: 00010000

- 52: 00110100

- 119: 01110111

Step 2: Determine the subnet mask

- /19 corresponds to:

255.255.224.0, or in binary:

11111111.11111111.11100000.00000000

Step 3: Calculate the network address

Apply the mask:

- IP: 11010111.00010000.00110100.01110111

- Mask: 11111111.11111111.11100000.00000000

AND operation:

- Network address: 11010111.00010000.00100000.00000000, which is 215.16.32.0 in decimal

Step 4: Determine the broadcast address

Set host bits to 1:

- Host bits: last 13 bits (since /19 leaves 13 bits for hosts)

- Network bits fixed, host bits all 1s:

11010111.00010000.00111111.11111111

- Corresponds to: 215.16.63.255

Result for Subnet B:

- Network address: 215.16.32.0

- Broadcast address: 215.16.63.255

- Subnet mask: 255.255.224.0

Discussion

The calculations highlight how the subnet mask determines the network size and the range of IP addresses available within a subnet. For Subnet A (/20), the network supports up to 4094 hosts (2^12 - 2). In contrast, Subnet B (/19) allows for 8190 hosts (2^13 - 2). Selecting appropriate subnet masks depends on anticipated network size and security requirements, especially when dividing organizational departments such as development and marketing.

Understanding these details enables network administrators to optimize IP address utilization, enhance security segmentation, and facilitate efficient routing within a cloud environment like AWS VPC (Sitnik et al., 2020). Accurate subnetting is foundational for deploying scalable and secure cloud architectures, reflecting strategic planning in network design.

Conclusion

Calculating network and broadcast addresses alongside selecting appropriate subnet masks is a fundamental skill in network management and cloud architecture deployment. Through detailed binary and decimal computations, we determined that Subnet A's network address is 146.38.64.0 with a broadcast address of 146.38.79.255, and Subnet B's network address is 215.16.32.0 with a broadcast address of 215.16.63.255. These calculations are critical for efficient IP address planning and for ensuring network segmentation aligns with organizational needs, especially in cloud environments like AWS VPC.
