About NetEngToolkit

NetEngToolkit is a free, practical toolkit built for network engineers, system administrators, IT professionals, students, and anyone learning networking.

What we're building

Phase 1 focuses on the tools engineers reach for most often: subnetting and CIDR calculators, DNS lookups, and everyday diagnostics like HTTP status and header checks — all in one fast, ad-free, account-free place.

Our principles

• Calculations that can run in your browser, run in your browser. Nothing is sent to a server unnecessarily.
• We never fabricate a result. If a lookup or diagnostic can't be completed, we say so clearly.
• No accounts, no unnecessary sign-ups, no tracking beyond what's needed to keep the site running.

Open development

NetEngToolkit is built for GitHub-based development and Cloudflare deployment, with a modular architecture designed to make adding new tools straightforward in future phases.
