AdGuard DNS
Network-wide ad and tracker blocking without installing software on each device.
Official siteAbout AdGuard
AdGuard DNS is operated by AdGuard Software Limited, a company best known for its desktop and mobile ad-blocking products. The DNS service launched in 2018 and is the natural choice when you want ad and tracker blocking applied to every device on a network — TVs, IoT devices, and apps that don't support traditional ad blockers.
Three endpoints are offered. The default (94.140.14.14) blocks ads, trackers, and a malware blocklist. The Family variant adds adult-content filtering. The Non-filtering variant returns all queries unmodified, which is useful as a fast unfiltered resolver from the same operator.
AdGuard publishes a transparency policy stating that no IP-level logs are retained and only aggregate, anonymized statistics are kept. The service supports DoH, DoT, and DNSCrypt. Performance varies by region; AdGuard's anycast network is smaller than Cloudflare's or Google's but generally adequate. Worth knowing: because the resolver actively blocks queries, some sites will appear "broken" if they depend on tracking domains for legitimate functionality. The Non-filtering endpoint exists for exactly this reason.
