MAC addressA normal web page cannot change your device MAC address. You can generate a random value for manual system configuration.

Network protection checks
Connection checkConfirms that this page can reach its own origin.
DNS resolver testLets you compare browser-visible DNS answers through supported DoH endpoints.
Request loggingLocal and opt-in. The page cannot see unrelated browser traffic.
DDoS protectionReal protection needs to run at the server, reverse proxy, CDN, firewall, or network edge. A webpage cannot add that protection to the whole device.
IP maskingActual public-IP masking requires a proxy or another network gateway. This page can only report the address visible to the browser.
MAC randomisationMAC randomisation is an operating-system or Wi-Fi stack feature, not something JavaScript in a webpage can switch on.
