Interactive Simulations
Step through TCP handshakes, ARP requests and OSPF convergence — frame by frame, in your browser.
An interactive curriculum for engineers, students and the curious. Build mental models that stick — through simulations, not slides.
We stripped the noise out of network education. What's left is the part where you build, break and observe.
Step through TCP handshakes, ARP requests and OSPF convergence — frame by frame, in your browser.
XP, streaks, and adaptive review surfaces what you don't remember yet — without the dopamine traps.
Drag routers and switches onto a canvas. Wire them up. Watch packets actually flow.
A real-feeling shell with ping, traceroute, dig and nmap — sandboxed and safe to experiment in.
A signed, verifiable credential when you finish. Shareable, embeddable, ready for LinkedIn.
Every lesson, simulation and quiz available in English and Türkçe — toggle anywhere, anytime.
Start with the physical wire. End with the modern internet. Unlock as you go.
Cables, frames, MAC addresses, switches and the bottom two layers.
IP addressing, subnetting, routing and the protocols that move packets.
TCP, UDP, congestion control and the contract beneath every connection.
DNS, HTTP, TLS, mail and the protocols you actually touch daily.
BGP, CDNs, QUIC, IPv6 and the architecture that holds it all together.
A signed certificate of completion — verifiable on-chain via a public registry, designed to live on your LinkedIn or résumé without looking like a participation trophy.
for the successful completion of all five levels of the Packet.School networking curriculum — twenty-two lessons, ten simulations and the final practicum.
Every lesson, every simulation, every certificate — free forever for individuals. Pay only when you bring a cohort along.
For anyone who wants to learn how the internet actually works.
For bootcamps, university labs and engineering onboarding.
For IT departments, universities and 50+ seat deployments.
Twenty-two lessons. Ten simulations. Zero cost. You can be looking at your first TCP handshake in under three minutes.
