What should I learn next?

A learning path sequences concepts, worked examples, knowledge checks and real labs so each one prepares you for the next. You can also browse the curriculum and choose individual activities when you already know where to focus.

All learning paths

Networking Fundamentals

Beginner

Start from nothing and finish able to read a routing table, segment a LAN with VLANs, run DHCP and DNS, and control traffic with NAT and access lists. Every concept is followed by a real network you configure yourself.

9 modules51 activities~12 h

Network Services in Depth

Intermediate

The three services every network runs - addressing, naming and translation - past the point where the fundamentals stop. Scopes and options, records and caching, and publishing a service inward rather than just sharing an address outward.

4 modules15 activities~5 h

Routing Protocols in Depth

Advanced

Past one static route and one OSPF adjacency, into the protocols as they actually behave - what they exchange, how they choose, and the specific ways each one fails while looking healthy.

9 modules41 activities~12 h

Network Security and Access Control

Intermediate

Filtering as it is actually practised - by service rather than by host, in the right direction, with state - and the controls around it that no device implements.

6 modules21 activities~6 h

Network Operations and Design

Intermediate

The parts of the job that are not configuration - how networks are shaped, what runs them, how they are watched, and what happens when they are automated or lost.
