How Penguin DNS Works

DNS is the internet’s phone book. When your kid types a site name or taps an app, the device asks a resolver: “Where is this?” The resolver answers with the address, and the device connects. It happens in milliseconds, hundreds of times a day, on every device you own.

Most homes use whatever resolver their internet provider set by default. That resolver answers every question it’s asked — including questions about adult sites, malware download pages, and phishing scams built to steal passwords. It filters nothing, and on many providers the lookups are logged and monetized.

Filtering at the source

Penguin DNS is a resolver with a rulebook. When a lookup arrives, we check the domain against constantly updated lists: adult content, malware and phishing, known scams, and aggressive trackers. Clean domains resolve instantly, exactly as before. Blocked domains return “not found” — so the browser, app, or game can’t connect at all. There’s no block page to click through and no software on the device to argue with or uninstall.

One setting covers the house

Because the filter lives in the resolver, you set it once — in your router — and it covers everything on your Wi-Fi: phones, tablets, laptops, school Chromebooks, smart TVs, and game consoles, including the devices that can’t run filtering apps. Guests on your network get the same protection automatically.
