Enterprise Network Design and Implementation Using Huawei Datacom Technologies

Cisco Packet Tracer project demonstrating network setup for Accounts and Delivery departments with proper IP addressing, routers, and switches.

Network configuration and troubleshooting exercises focusing on TCP/IP addressing, subnetting, and routing. 10 progressive levels covering subnet masks, CIDR notation, network segmentation, and routing tables. Part of 42 School curriculum.

This Packet Tracer lab demonstrates the configuration of OSPF (Open Shortest Path First) across a multi-router network. It includes tasks such as IP addressing, enabling OSPF on all routers, configuring loopback interfaces, setting passive interfaces, and configuring an ASBR (Autonomous System Boundary Router) to advertise a default route.

NetPractice is a hands-on networking project featuring 10 progressive levels that teach essential computer networking fundamentals. Through interactive problem-solving, you'll master TCP/IP addressing, subnet masks, default gateways, routing, and OSI layers by troubleshooting and configuring non-functioning network diagrams.

This repo contains the basics of interview quesrtions based upon computer networks. It includes network models, transmission media, network topologies, and routing algorithms. Understand the concepts of network security, network performance, and quality of service

NetPractice is a networking project from the 42 curriculum focused on understanding how IP addressing, subnetting, and routing work in computer networks. The objective is to configure network settings and solve routing exercises by applying networking concepts such as IP ranges, masks, and gateways to ensure proper communication between devices.

Networking fundamentals, IP addressing, subnetting, and routing logic (42 Vienna)

This repo contains my Computer Networks course's labs and project I did in my university.

Designed and configured a basic inter‑departmental network using Cisco Packet Tracer. Built connectivity between the Accounts and Delivery departments using a router and switches, implemented correct IP addressing and subnetting, and verified communication between all devices through ping tests.

Professional IPv4 & IPv6 Subnet Calculator built with HTML, CSS & JavaScript. Features binary view, address classification, click-to-copy results, and full CIDR support for fast and accurate subnet calculations.
