An offline subnetting quiz for CCNA, Network+, and other certification candidates. Questions are randomly generated, answers are deterministic, and every calculation is hand-verified. It drills the "magic number" / block-size method I memorized before my own exams: built for speed and repetition. Features: - Built-in block-size ("magic number") reference, one tap away - Five question types: network address, broadcast, first and last usable host, usable host count - Multiple choice or written answers - or a mix of both - SESSION and TOTAL counters, plus a per-type accuracy breakdown - Optional daily practice reminder - Fully offline - no accounts, ads, tracking, or subscriptions - Shamelessly vibe coded using Fable 5; the subnet math lives in its own package and is hand-verified for accuracy About me: I'm a working network engineer and active CCNA, living in Arizona, USA. Questions, feedback, or bug reports? I read and reply to every email personally.
