Subnetting Course

Interactive tools I built with Claude to learn each topic. I kept asking questions and reworking them until they actually made sense to me, so they explain things in a simple, easy-to-follow way. Free to use, and your progress saves in your own browser.
OSI Layers
Helps you learn the 7 OSI layers and which layer things like MAC addresses, ports and HTTP belong to.
