AdGuard Home

AdGuard Home is a network-level Domain Name System (DNS) filtering and ad-blocking software platform that functions as a self-hosted DNS server for blocking ads, trackers, and malicious domains across devices on a local network (network security / DNS filtering).

  • Self-hosted DNS server with configurable filtering rules for ads, trackers, and malicious domains (network security / DNS filtering).
  • Network-wide ad and tracker blocking for all connected devices, including those that do not support browser extensions (network security / privacy protection).
  • Customizable blocklists, whitelists, and user rules with support for filter subscriptions and domain-based policies (policy management).
  • Web-based management UI for configuration, monitoring, and log review, including statistics on DNS queries and blocked requests (observability / admin console).
  • Support for encrypted DNS protocols such as DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) for secure DNS resolution where documented (network security / encrypted DNS).

More About AdGuard Home

AdGuard Home is a self-hosted DNS filtering solution that operates at the network layer to block advertising, tracking, and access to malicious domains before traffic reaches individual devices. It is deployed as a DNS server on premises or on a home or small-office network gateway and routes DNS queries from client devices through its filtering engine, providing network-wide ad and tracking protection without requiring client-side browser extensions.

The core functional area of AdGuard Home is DNS-based filtering (network security / DNS filtering). Administrators can configure the software to use filter lists that contain domains associated with advertising, analytics, tracking, phishing, and other unwanted categories. When a client device resolves a domain, AdGuard Home applies these rules and either returns a blocked response or forwards the query to upstream DNS resolvers. This model supports central control of domain access policies across all devices, including smart TVs, mobile devices, and Internet of Things (IoT) hardware that may not support traditional ad-blocking tools.

AdGuard Home provides a web-based administration console (observability / admin console) that exposes configuration options and operational telemetry. Through this interface, administrators can review DNS statistics, including total queries, blocked requests, queried domains, and per-client metrics. The console also supports configuring upstream DNS servers, encrypted DNS transport where available, and various options for handling blocked domains, such as returning a null response or redirecting to a specified address.

Filtering configuration in AdGuard Home includes support for blocklists, allowlists, and user-defined rules (policy management). Administrators can subscribe to external filter lists compatible with the AdGuard ecosystem or other DNS blocklist formats, and they can define local overrides to allow or block specific domains for particular clients or globally. The rule engine operates on domain names and can be tuned to accommodate application compatibility requirements or organizational security policies.

AdGuard Home also supports encrypted DNS protocols such as DNS-over-HTTPS and DNS-over-TLS (network security / encrypted DNS), where documented in official materials. This capability enables secure communication between client devices and the AdGuard Home instance or between AdGuard Home and its upstream resolvers, reducing the risk of DNS tampering or passive observation on the network path. Administrators can configure certificates and endpoints to expose these encrypted DNS services internally or externally.

In enterprise or institutional environments, AdGuard Home can serve as a component of network security and privacy architecture for smaller offices, lab networks, or department-level segments. It can be integrated into local DNS resolution flows, either as the primary resolver for clients or as an intermediate filtering layer in front of recursive resolvers. Its logging and statistics support monitoring of domain usage patterns, while the filtering model supports enforcement of acceptable-use or security policies focused on DNS-level control rather than Deep Packet Inspection (DPI).

From a directory and categorization perspective, AdGuard Home belongs in network security and infrastructure tooling, specifically under DNS filtering, content blocking, and privacy protection. It provides DNS-layer ad blocking, tracker blocking, and domain-based access control that can augment existing firewall and endpoint security stacks, particularly in environments where administrators prefer self-hosted, policy-driven DNS filtering under their direct control.
