Hi Product Hunt! I’m Shota, an infrastructure engineer from Japan. Subnet Ninja is my first Windows app. I built it to stop bouncing between Excel and multiple subnet calculators while planning CIDR blocks. Free: fast on‑prem IPv4 subnet math. Pro: AWS/Azure/GCP reserved‑IP aware modes, a CIDR split tree, and CIDR overlap checks. I’d love your feedback: what should I build next—IPv6 support or better export (CSV/JSON)? If you pick “export”, what format do you use most?
