94.140.14.14: AdGuard DNS

94.140.14.14 is the primary address of AdGuard DNS in its default configuration, which refuses to resolve domains on AdGuard’s ad and tracker blocklists. It is free, needs no account, and is run by AdGuard Software Limited, the Cypriot company behind the AdGuard ad blocker.

What the filtering covers

AdGuard maintains its own blocklists, the same ones its browser extension and desktop applications use, and applies them at the resolver. A lookup for a domain on those lists returns a null answer rather than the real address, so the request never leaves the device.

Working at the DNS layer buys reach and loses precision. Reach, because a smart TV, a games console, or a mobile app cannot install a browser extension but does use DNS. Precision, because the resolver only sees a domain name. A tracker hosted on the same hostname as the page content is invisible to it, which is why DNS blocking does not remove ads from large video platforms.

The address family

Pair	Behaviour
94.140.14.14, 94.140.15.15	Default: ads and trackers blocked
94.140.14.15, 94.140.15.16	Family: the default lists plus adult content and safe search enforcement
94.140.14.140, 94.140.14.141	Non-filtering: plain resolution, useful for testing

IPv6 equivalents exist under 2a10:50c0::, with ad1 and ad2 suffixes for the default pair.

When you see it

• In router DNS settings on networks where someone wanted household-wide ad blocking without running a server.
• In Android’s Private DNS field, usually as a hostname rather than the raw address.
• In AdGuard Home or Pi-hole upstream configuration.
• In a support ticket, when a site fails to load and the resolver is the first thing to rule out.

How to configure it

1. Router: 94.140.14.14 and 94.140.15.15 in the LAN DHCP DNS fields, which covers every device including ones with no DNS setting of their own.
2. Windows and macOS: the same pair in the adapter’s IPv4 DNS settings.
3. Android 9 and later: Private DNS provider hostname dns.adguard-dns.com for DNS over TLS.
4. iOS: install AdGuard’s DNS configuration profile, or set the addresses per Wi-Fi network under Configure DNS, Manual.
5. Encrypted on a laptop: https://dns.adguard-dns.com/dns-query for DNS over HTTPS, which keeps working on other people’s networks.

Privacy and policy

AdGuard Software Limited is registered in Cyprus and therefore within the EU’s GDPR regime. The AdGuard DNS privacy policy states that the public resolvers do not log IP addresses and that AdGuard keeps anonymised aggregate statistics about query volume and blocked domains. Query history tied to an account only exists in the paid private DNS product, and only when the account holder turns it on.

What it is not

Pointing a device at 94.140.14.14 does not hide your IP address or encrypt your traffic beyond the DNS lookups themselves. It is not a parental filter in the default configuration either; that needs the family pair. And it is not a complete ad blocker, so a browser extension still has work to do on pages where ads and content share a hostname.

If a site misbehaves after switching, compare the answer from a filtering and a non-filtering resolver in /dns-lookup.
