Resolver Check
The check uses unique DNS names so cached results should not affect the outcome.
No result yet.
Manual DNS Setup
Managed devices should normally receive DNS settings automatically from their network or device profile. If that did not happen, use the resolver details from the internal setup notes for the network you are connected to, then run this check again.
Expected resultA managed resolver name means this browser is using the intended DNS path for that network.
Public resolver resultCloudflare, Google, Quad9, NextDNS, or another public resolver means private names and local filtering may not behave as expected.
Filtered vs. plainUse the filtered resolver unless you intentionally need the unfiltered fallback.
