About AdGuard

AdGuard public DNS is a set of free DNS servers that filter domain lookups to block ads, trackers, malware, and adult websites. Users point a device or network at one of three servers: a default server that blocks ads and trackers, a non-filtering server that blocks nothing, or a family protection server that also blocks adult content and enables Safe Search and Safe Mode where possible. The page gives setup steps for Android, iOS, macOS, and Windows, including a configuration profile for iOS and macOS that can choose DNS-over-HTTPS or DNS-over-TLS encryption.

The page's recommended route is installing the AdGuard Ad Blocker app, which lets users select AdGuard DNS in its server settings without entering server addresses. The app adds ad blocking and tracking protection beyond DNS. Manual setup applies only at the DNS level, so it does not cover every type of advertising or tracking.
