How to Check Whether Your Router's DNS Filtering Covers Your Devices

Computer
Check while on home Wi-Fi. Browsers can have their own secure lookup setting.
Phone
Check on Wi-Fi, not mobile data. Private DNS settings may override the router.
TV
Smart TVs and streaming boxes may use built-in lookup services.
Changing your router's DNS settings can help block unwanted websites across your home. But some devices and apps use their own settings.
Check one device at a time. A passing test on your laptop does not prove that your TV uses the same filter.
First, save your old settings
Your router is the box that connects your home devices to the internet. Before changing it:
- Pick a time when nobody needs an important call or connection.
- Take a private photo of the current DNS settings.
- Follow instructions for your exact router model.
- Use only the DNS addresses shown for your household.
DNS helps your device find websites. An internet address is the location where a web page or server can be found on the internet.
Router menus use different names. Look under Internet, Network, Advanced or WAN. WAN means the router's connection to the internet.
If you cannot find the setting, leave your working connection alone and ask support.
Check your computer
Connect to your home Wi-Fi or use a network cable.
Run the filtering service's supported connection check. Where available, check its activity log too. Look for a fresh request from your test, rather than an old result.
Use a safe blocking test, not a real harmful website.
With Datante, a browser check can confirm filtering in that browser at that moment. It cannot confirm every app or device in your home.
Check your phone and TV separately
A phone may quietly switch from Wi-Fi to mobile data. Make sure it stays on your home Wi-Fi while you test.
A guest Wi-Fi network may use different settings from your main Wi-Fi. Check it separately.
For a TV, open a normal app and note the time. Look for matching activity if your service provides it. If several devices are busy, a household activity log may not tell you which one made a request.
Datante can group activity into likely device families, such as TV brands. A likely family is not proof of one particular TV. If you cannot confirm a device, write “not confirmed” instead of guessing.
Watch for settings that take a different route
These are the common ones:
- IPv4 and IPv6: two kinds of internet addresses. Your router may have separate DNS settings for each.
- Secure DNS or Private DNS: a browser or phone can choose its own website lookup service instead of the router's.
- VPN: it may use a different DNS service when switched on.
Follow supported instructions for the address types your service provides. Do not switch off important security features just to get a green test result.
AdGuard's guide explains why DNS filtering depends on which service handles the lookup.
Keep a short checklist
| Device | On home Wi-Fi or cable? | Filtering checked? | Notes |
|---|---|---|---|
| Computer | ______ | ______ | ______ |
| Phone | ______ | ______ | ______ |
| TV | ______ | ______ | ______ |
Keep this record private. Do not post your household's activity history.
If something stops working, change one setting at a time. Your device may remember an old website address for a while, so results may not change right away. A page reload or a short wait can help.
Use a temporary pause or a carefully chosen exception when troubleshooting. Resume filtering afterward. If you cannot get back online, restore your saved settings and contact support.

About these checks
This is a checklist to use at home, not a report of completed device tests. A passing result applies to the device, app and connection tested. Settings can change after software updates or when a VPN starts, so check again when something changes.
