## What is Learnet?

Learnet is a learning app that makes networking fundamentals stick by "read first, then solve."

Every topic follows the same flow: a short illustrated lesson first, then a quick quiz to check your understanding. The lessons lean on hand-built diagrams and animations — packets traveling through a router, an L2 switch learning MAC addresses, the bits of a subnet mask — so the ideas click instead of having to be memorized.

WHO IT'S FOR
- New IT / infrastructure engineers, and anyone studying for Network+ or CCNA
- Anyone who wants to turn a vague sense of how communication works into a clear one

TOPICS (24 total)
Free: How communication works / The OSI model / The physical layer & LAN cables / MAC addresses / IP addresses / Subnets & CIDR / ARP / L1-L2-L3 switches / Unicast, broadcast & multicast / VLAN / The default gateway / Ping / Routing / Wi-Fi / IPv6
Learnet Pro: Port numbers / Firewalls / TCP & UDP / DNS / DHCP / NAT & NAPT / Proxy servers / HTTP / HTTPS

WHAT MAKES IT WORK
- Short, illustrated lessons with custom animations
- Confirmation quizzes that check real understanding
- One topic at a time, perfect for spare moments
- A learning streak, spaced-repetition review, and badges to keep you going
- Hands-on practice with real commands (ping, traceroute, arp, netstat, curl, dig, and more) so you can see the concepts on your own machine

LEARNET PRO (one-time purchase, no sub
- Unlocks all advanced topics (port numbers, TCP/UDP, DNS, DHCP, NAT, firewalls, proxies, HTTP, HTTPS)
- Removes ads so you can focus on lear

The free version includes ads (Google AdMob). Buying Pro removes them.
