Short answer
In the Google Home app, tap Wifi › Network settings › Advanced networking › DNS, choose Custom, paste your Sheepdog Filter address and save. Then turn IPv6 off under Advanced networking › IPv6.
Before you start
You'll need the app or login for your router, and about five minutes. In your Sheepdog Filter dashboard, open Devices › + Protect something › Everyone at home. That links your home internet to your account and shows your DNS address with a Copy button. On a computer, scan the QR code with your phone to open the addresses there, so you can paste instead of typing.
Step 1: Find the DNS setting
- Open the Google Home app.
- Tap Wifi, then Network settings › Advanced networking › DNS.
- Choose Custom.
Step 2: Fill in the boxes
- Primary DNS: paste your Sheepdog Filter address.
- Secondary DNS: leave it empty. If it won't save empty, paste the same address again. Never put Google (8.8.8.8) or your internet company's address there, or devices will slip around the filter.
Tap Save. No restart needed: the router passes the change to every device within a minute or so, and your dashboard turns green by itself when it sees your router.
Step 3: Turn IPv6 off
In the Google Home app: Wifi › Network settings › Advanced networking › IPv6, switch it off and save. Your internet works the same without it, and it stops phones and laptops quietly going around the filter. (Rather keep IPv6? Your dashboard also gives your family its own IPv6 DNS address to use instead.)
Google's Family Wi‑Fi features
Google Home's device groups and schedules can pause Wi‑Fi for a group of devices. They work fine alongside Sheepdog Filter, which adds category and app blocking, bedtime, homework mode and weekly reports.
What this covers, and what it doesn't
Router setup covers every device on your Wi‑Fi: phones, tablets, TVs, consoles, smart speakers and visitors. It doesn't cover phones on mobile data or at friends' houses, so for your kids' own phones, also set up the device: see iPhone and Android.
Want grown-ups' devices unfiltered? In the dashboard, mark your own phone or laptop as a grown-up device and the home rules won't apply to it.

Start freeQuestions parents ask
Will changing DNS slow down my internet?
No. DNS lookups take milliseconds and happen once per site. Streaming and downloads go straight to the internet as normal.
What if my home internet address changes?
Sheepdog Filter notices when your internet company changes your home's address and re-links your router automatically.
