Development of a Network Subnetting System for Enhanced Connectivity and Data Management in Barobo LGU

In today’s digital era, local government units (LGUs) depend on reliable networks to manage data and deliver public services efficiently. The Municipality of Barobo in Surigao del Sur faces communication delays, data management inefficiencies, and slow network performance due to a lack of structured network design. This study proposes the development and implementation of a subnetted network system tailored to the LGU’s needs. Subnetting divides the network into smaller, more manageable segments, improving performance, security, and fault isolation. The proposed design utilizes a Cisco 2911 router and two switches, connecting five offices and 25 computers across two floors. Each floor is assigned a /27 subnet, allowing efficient IP address allocation and future scalability. The system enhances data flow, simplifies administration, and reduces network congestion without requiring complex configurations like VLANs. With projected uptime of 99.9%, the solution supports essential operations and ensures reliable communication across departments. The study emphasizes practical implementation, cost-effectiveness, and ease of maintenance, making it ideal for public sector environments. By adopting this subnetting strategy, the Barobo LGU can achieve streamlined operations, better service delivery, and readiness for future digital expansion.
