Networking
Learn practical computer networking: IP addressing, Ethernet, switching, routing, OSPF, network services, and troubleshooting workflows.
PRACTICAL LEARNING PATH
What you will learn
Networking work becomes easier when every symptom is tied to a layer, a device, and observable evidence. This path develops that operating model before moving into IPv4 and IPv6 addressing, Ethernet switching, VLANs, routing, OSPF, and the services that keep networks usable.
The lessons use the same questions engineers ask during real incidents: Is the interface up? Did the host receive the correct address? Is the switch forwarding the VLAN? Did the router install the expected prefix? Each topic connects the concept to commands, packet behavior, and a result you can verify.
