## What is Internet 3D Explorer?

See the Internet, don't just read about it.

Internet 3D Explorer turns the invisible machinery of the Internet into a place you can fly through, tap, and take apart. Instead of static diagrams in a textbook, you get a living, three-dimensional model of the public Internet — every device, cable, server, and protocol rendered as an object you can rotate, zoom into, and select for a full explanation of what it is, how it works, and why it matters.

WHO IT'S FOR
Students studying networking, IT professionals prepping for certifications, educators looking for a better way to teach the OSI model, or anyone who's ever wondered what actually happens between typing a URL and a page loading on screen.

EXPLORE A FULLY INTERACTIVE 3D WORLD
Fly, rotate, and zoom through a navigable model spanning every layer of Internet infrastructure — end-user devices, home and enterprise networks, Wi-Fi and routers, ISPs, backbone providers, undersea cables, Internet Exchange Points, Autonomous Systems and BGP routing, the DNS hierarchy, CDNs, data centers, cloud infrastructure, load balancers, and application services like email and streaming. Tap any object for a plain-English breakdown: what it is, its purpose, how it works, why it's important, and how it connects to everything around it.

TRACE REAL PACKETS, HOP BY HOP
Go beyond the big picture with a true packet-level simulator. Step through the exact sequence of real packets sent when a device loads a secure website — DHCP address assignment, ARP resolution, the full recursive DNS lookup, the TCP three-way handshake, the TLS handshake, and the HTTP exchange itself. Every packet shows its real source and destination addresses, header fields, and a plain-English explanation, and the whole session stays lit up on the network diagram as a growing trail so you can trace the entire journey from the very first packet.

A CLEAR 2D DIAGRAM, ZOOMABLE AND PANNABLE
Switch to a flat, end-to-end schematic view of the same network — a classic topology diagram you can pinch to zoom and drag to pan, ideal for seeing the complete architecture at a glance or studying for an exam.

GUIDED LEARNING, AT YOUR PACE
- Guided tours from beginner to advanced, narrated stop by stop through key concepts
- Step-by-step demos of everyday activities — loading a website, sending an email, making a video call, streaming a movie
- Layer visibility controls to isolate networking, security, routing, DNS, cloud, or application components
- Instant search that flies you straight to any component
- A built-in glossary of networking and Internet terminology
- Quizzes across five topic areas to test what you've learned

LEARN EVERY MAJOR PROTOCOL
IP, TCP, UDP, HTTP, HTTPS, DNS, DHCP, ARP, ICMP, TLS, SMTP, IMAP, POP3, FTP, and SSH — each with a clear explanation of what it does and why it exists.

WHY INTERNET 3D EXPLORER
- Learn by exploring, not memorizing
- Real, technically accurate detail — not oversimplified cartoons
- Works equally well on iPhone and iPad
- No account, no subscription, no ads
- Built for curious minds of every level, from first-time learners to working engineers

The Internet runs the modern world. Now you can finally see how.
