What's Next

You now have the roadmap and the mindset.

You know what a network stack is, which layers you'll build, and how your Docker lab will keep everything safe and reproducible.

Next: Module 1 — Setting Up Your Lab

You'll:

• Build the two-container sandbox (client ↔ stack)
• Learn how TAP interfaces connect user-space programs to virtual Ethernet frames
• Run a "smoke test" to confirm packets can flow between containers

Once that's working, you'll have the perfect playground to start your first real implementation — Ethernet and ARP in Module 2.

Checkpoint

Commit your repo now (tag it v00_orientation) so you can always return to this clean starting point:

git add .
git commit -m "Module 0 – Orientation complete"
git tag v00_orientation

Success: Then move on to Module 1 — where theory meets your first running packets.
