AbidineBariyaa/Network-Tools — reverse-engineered prompt

I want a simple browser based network tools page, ideally in German, that feels like one handy place for basic network related checks and lookups. Keep it clean and easy to use, something a normal person could open and understand right away without setup headaches. A single page app is fine if that fits.

Please make it feel practical, with clear inputs, obvious buttons, and results that are readable instead of overly technical. If some tools need live data or external services, use the lightest sensible approach and make sure errors are explained in plain language. Add a small intro so people know what the page is for, and make the layout work well on desktop and mobile.

If there is already a starting file in the project, build on that rather than starting from scratch. Keep the code organized and easy to edit later. If you need to, look up current docs online and wire up whatever is needed to make the page actually usable.
