Cisco Packet Tracer lab on VLSM subnetting and static routing, including subnetting the 192.168.5.0/24 network and configuring routes for full PC connectivity across multiple LANs.

A complete, structured, and beginner-to-advanced networking book for ethical hackers and penetration testers. Covers Networking, IP addressing, tools, and real-world offensive use cases — created by Muhammad Saqlain (Dark Wolf).

GNS3 lab documenting internal Apache2 web server deployment. Includes Cisco IOSv router, switch, and QEMU Xubuntu clients with SSH access.

GNS3 lab integrating Windows Server network services, including DHCP for dynamic IP assignment, HTTP (IIS) for internal web hosting, and DNS for local name resolution between clients.

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.

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.

Basic GNS3 lab documenting fundamental networking concepts. Includes Cisco IOSv router, switch, VPCS, and QEMU Xubuntu client.

The Internet Assigned Numbers Authority (IANA) performs the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. IANA maintains the protocol registries, top-level domain delegations, time zone database, and language subtag registry that the Internet relies on.

Enterprise Network Design and Implementation Using Huawei Datacom Technologies

Networking troubleshooting labs covering TCP/IP, DNS, DHCP, subnetting, VPN, and basic network diagnostic commands.

Networking fundamentals project from 42 curriculum covering IP addressing, subnetting, and routing configuration.

Configuring small networks. Through this project, you will learn the fundamentals of how addressing works with the TCP/IP protocol, by solving practical cases that simulate real network environments.

This repository contains Agief Prakasa Nurdien's AoL (Assurance of Learning) Case Study for CPEN6247001 – Computer Networks course. The project covers 3-floor network design, including devices, IP addressing & subnetting, routing, and application layer setup, simulated using Cisco Packet Tracer. (AoL score: 85, grade: A-).
