I'm currently working IT Service Desk, and my next step is moving into networking or systems administration. Studying for the CCNA has meant a lot of flashcards, a lot of practice problems, and a lot of subnetting math done by hand — so I decided to build the tool I actually wanted while studying.
This trainer generates random subnetting problems and walks you through the magic-number method until it clicks. No login, no fluff — just practice.
Thanks for stopping by.
