How DNS filtering works
Whenever a phone or computer connects to an online service, it usually asks a DNS service to find that destination. A family DNS filter checks the requested domain against the household’s rules. Allowed destinations continue normally; blocked destinations do not resolve through the filter.
What families can control
- Pornographic and other unwanted website categories
- Safe Search on supported search engines
- Specific websites that should always be blocked or allowed
- Household defaults with different rules for a particular device
Why families choose it
DNS filtering works across browsers and many apps because it operates at the network-request layer. When configured directly on a supported device, it can continue working away from home without requiring a traditional monitoring app.
Its honest limits
DNS filtering can identify requested domains and whether the filter allowed or blocked them. It cannot read messages, see the exact content inside an app, measure screen time, or establish why a person’s device contacted a service.
