Networking Fundamentals Through Hands On Labs: Understand Ethernet, IP Addressing, Routing, and Troubleshooting Step by Step

Understand what your network is doing—and learn how to prove it.

Why can two computers on the same switch fail to communicate? Why does a successful ping not guarantee a working website? And why can a router reach a destination while a client cannot?

Networking Fundamentals Through Hands On Labs answers these questions through one growing laboratory. Start with two hosts and a switch, add routed networks, explore IPv6 and application services, and practice diagnosing faults from evidence.

Inside you will find:

• 15 labs with clear starting states, verification steps, recovery instructions, and worked solutions.
• IPv4 subnetting and VLSM explained through examples and checked address plans.
• Ethernet switching, ARP, routing, IPv6, TCP, UDP, DNS, and DHCP connected into one practical learning path.
• Original diagrams, packet-analysis exercises, and a local Python transport experiment.
• 48 checkpoint questions with explanations and six troubleshooting case studies.

Written for beginners, students, and aspiring IT support technicians. No previous networking experience is required. The device labs use an isolated Cisco IOS style simulator; software is not included. This is an independent introduction, not an official certification guide.

Build a small network you can explain, then learn to find out exactly why it stops working.
