Where Does Android Store the Private DNS Hostname?
Where Android keeps the Private DNS hostname, system setting plus ADB roles. Exact folders are covered below.
Last updated
Android Private DNS is a system toggle with a hostname string. Your resolver choice lives in global system settings. Modes cover off, automatic, and a named provider.
Same Google backup does not always restore this toggle, so note it manually. Exact menu names shift with Android skins. Keep the hostname written down during moves. If browsing breaks on new WiFi, check this setting first. A stale hostname from an old provider blocks every lookup silently. Check the in app storage readout when sizes look wrong on different releases.
Where Android Private DNS stores this, by platform

Frequently asked questions
How do I find my Private DNS hostname?
Open Settings then Network and internet then Private DNS to view the hostname. The value lives in system settings, readable over ADB with settings get global private_dns_mode. Back up with a screenshot, since full device backups skip some system toggles.
Does Private DNS keep query logs?
No. Private DNS points at your chosen DoT resolver without keeping logs itself. The phone holds the hostname plus mode. Query logs live with the resolver operator where logging is on. Reinstalls never apply, since this is a system toggle, not an app.
