Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. For home-network DNS resolution, first query the same hostname from two devices and a reputable alternate resolver.
What this covers
- home-network DNS resolution with this exact failure state
- Diagnosis across site/provider outage versus resolver, filter, VPN and cache
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. Expected behavior: translate public hostnames consistently over IPv4 and IPv6.
Isolate the component boundary
ReversibleQuery the same hostname from two devices and a reputable alternate resolver. Use a known reference input or manufacturer test and compare the result. Boundary to separate: site/provider outage versus resolver, filter, VPN and cache.
Correct only the proven cause
ReversibleCorrect the failed resolver/filter or restart the router/client cache. Correct the setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. Do not bypass managed security DNS without administrator approval.

Common follow-ups
What should I check first when home-network DNS resolution has this problem?+
Query the same hostname from two devices and a reputable alternate resolver.
Why not factory-reset immediately?+
The useful boundary is site/provider outage versus resolver, filter, VPN and cache. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not bypass managed security DNS without administrator approval.
