Pi-hole works at the DNS level, which means it blocks ads for every device on your network — smart TVs, phones, game consoles, IoT devices — without installing anything on them. It works by acting as the DNS resolver for your LAN and returning <code>0.0.0.0</code> for known ad and tracking domains instead of the real IP.</p> <p>The side effect is that you also get a full picture of every DNS query every device makes, which is genuinely eye-opening. You will quickly discover that your smart TV is phoning home every few minutes.</p>
