I Built a Networking Cheat Sheet Because Nothing Else Worked

If you’ve ever tried to look something up mid-troubleshoot and ended up with 18 browser tabs and no memory of what you were originally trying to fix, this one’s for you. I built a personal networking reference guide because nothing out there was written for the way I actually learn: broadcast eng background, IP networking picked up on the job, and zero patience for documentation that assumes you already know what you’re searching for. The app covers subnet math, Cisco IOS commands, Wireshark filters, common port numbers, and broadcast-specific references like StudioHub pinouts and PTP IEEE 1588. It runs locally, it’s fast, and writing the prompts to build it turned into its own learning method. If the right resource doesn’t exist for your brain, you can build it now.
