Identify the core assignment prompt and clean it: remove any instructions, grading criteria, due dates, repetitions, meta-instructions, and extraneous content. Keep only the actual task and essential context.
The core assignment is to analyze subnetting conventions, specifically for a given IP network, including calculating subnets and providing specific subnet information.
The cleaned assignment instructions are: Analyze subnetting conventions with a focus on IP network segmentation. For a specified IP network (e.g., 208.101.170.0/24), subnet it into 16 subnets, and provide details for subnets #1, #4, #5, and #16. Show your calculations, including subnet masks, network addresses, broadcast addresses, address ranges, and number of hosts per subnet.

Subnetting, a fundamental concept in network management, involves dividing a larger IP network into smaller, manageable subnetworks to optimize performance, improve security, and efficiently allocate IP addresses. Understanding subnetting conventions is vital for network administrators, especially when implementing scalable and efficient IP addressing schemes, as in the case of BallotOnline's network infrastructure.
Introduction to Subnetting
At its core, subnetting allows the partitioning of IP address spaces, which helps mitigate issues such as broadcast domain size and IP address wastage. An IP address consists of two main components: the network portion and the host portion. By borrowing bits from the host portion, network administrators can create multiple subnets within a larger network. This hierarchical structuring enhances network security, simplifies management, and supports growth.
Subnetting Conventions and Techniques
The process of subnetting relies heavily on understanding subnet masks, which determine how many bits are allocated to the network and host parts. The subnet mask is a 32-bit number that can be expressed in decimal notation (e.g., 255.255.255.0) or in CIDR (Classless Inter-Domain Routing) notation (e.g., /24). CIDR allows for flexible subnetting without being constrained by traditional class boundaries, making it essential for modern networks.
Variable Length Subnet Mask (VLSM) further refines subnetting by enabling different subnets within the same network to have different masks, optimizing IP address utilization.
Application to a Specific Network: 208.101.170.0/24
Given the IP network 208.101.170.0/24, the goal is to divide it into 16 subnets. Since "/24" indicates that the first 24 bits are devoted to the network, the remaining 8 bits are for hosts. To create 16 subnets, we need to borrow 4 bits from the host bits because 24 = 16.
Adding these 4 bits to the network portion results in a new subnet prefix of /28, which provides \( 2^4 = 16 \) subnets, each with \( 2^{4} - 2 = 14 \) usable host addresses (subtracting network and broadcast addresses).
Calculating Subnet Details
Subnet Mask: /28 translates to 255.255.255.240 in decimal notation.
Number of Hosts per Subnet: 14 (24 - 2)
Number of Subnets: 16.
Subnets Breakdown and Specifics
Subnet 1:
- Network Address: 208.101.170.0/28
- Range of Usable IP Addresses: 208.101.170.1 – 208.101.170.14
- Broadcast Address: 208.101.170.15
Subnet 4:
- Network Address: 208.101.170.48/28
- Range of Usable IP Addresses: 208.101.170.49 – 208.101.170.62
- Broadcast Address: 208.101.170.63
Subnet 5:
- Network Address: 208.101.170.64/28
- Range of Usable IP Addresses: 208.101.170.65 – 208.101.170.78
- Broadcast Address: 208.101.170.79
Subnet 16:
- Network Address: 208.101.170.240/28
- Range of Usable IP Addresses: 208.101.170.241 – 208.101.170.254
- Broadcast Address: 208.101.170.255
Calculations Explanation
The total number of subnets is determined by the number of bits borrowed from the host portion. Starting with a /24 network, borrowing 4 bits yields 16 subnets. Each subnet's block size is 16 addresses, as dictated by the last 4 bits being reset to zero for the network address and all ones for the broadcast address. This yields a predictable pattern where subnet network addresses increment in steps of 16.
Thus, subnet 1 begins at 208.101.170.0 and ends with 208.101.170.15, with usable host addresses from 208.101.170.1 to 208.101.170.14. Similarly, subnet 4 starts at 208.101.170.48, and subnet 16 at 208.101.170.240, ensuring systematic addressing with minimal wastage.
Implications for Network Management
Efficient subnetting allows BallotOnline to segment its network into manageable sections, enhance security through isolation, and allocate IP addresses effectively. This approach reduces broadcast traffic, simplifies troubleshooting, and accommodates future expansion.
Furthermore, understanding subnetting conventions empowers network professionals to plan scalable network architectures, ensuring they meet organizational needs without exhausting IP space or creating unnecessary complexity.
Conclusion
Effective subnetting is crucial for modern network design, especially in organizations like BallotOnline that require scalable and secure IP management. By applying standard conventions, calculating subnets correctly, and understanding the technical parameters involved, network administrators can optimize resource utilization and ensure reliable connectivity across organizational or service provider networks.
