What this page needs
This tool computes entirely on your device, so nothing you type is sent anywhere. That local computation needs JavaScript; CSS is used for layout and theming.
This tool is built to also work over an HTTP API. Processing is currently off, so the API is documented but not served; when it is switched on, you will be able to call it without a browser.
All results are computed locally from the address and prefix you enter, using standard IPv4 addressing arithmetic. Nothing is looked up remotely and nothing is sent anywhere.
