AdGuard DNS DNS servers

AdGuard DNS offers 3 service variants with different filtering, reachable over DNS (53), DoT, DoH. Every address and endpoint below is taken from the operator's documentation; the behaviour is what we measured on 2026-09-24.

Measured

What we observed

Measured 2026-09-24 from one vantage point, three rounds per address, majority result. Anycast resolvers can behave differently from other networks. How we test

DNSSEC validation Validates

Returned SERVFAIL for dnssec-failed.org, rhybar.cz and badsig.go.dnscheck.tools on every address that answered, while resolving example.com.

Client subnet (ECS)

Sends /24. The authoritative server received that much of the client address, enough to locate a user to a block of addresses.

Plain DNS and NXDOMAIN

6/6 documented IPv4 addresses answered on port 53. Random non-existent names came back as NXDOMAIN, so errors are not rewritten into ads or search pages.

Networks

Which networks carry it

The announcing network comes from RIPEstat routing data for each documented address. The query network is where the resolver sent its own lookups during our probe, which a DNS leak test reports.

Check it

Confirm your device is using AdGuard DNS

Changing a DNS setting does not guarantee your lookups reach that resolver: a VPN, a browser's own secure DNS or a proxy can send them elsewhere. Our DNS leak test shows which resolvers actually received your queries.

From a terminal

# Which address did the resolver query from?
dig +short whoami.akamai.net @94.140.14.14

# Does it pass your subnet on (ECS)?
dig +short TXT o-o.myaddr.l.google.com @94.140.14.14

# Does it validate DNSSEC? SERVFAIL means yes
dig dnssec-failed.org @94.140.14.14

Behind a proxy

With an HTTP proxy, or a client set to socks5h://, the proxy side resolves hostnames, so your own resolver setting does not apply to that traffic. With socks5:// in curl or Python requests, your device resolves names first. The SOCKS5 vs SOCKS5h guide shows how to check which one you have.

Questions

AdGuard DNS questions

What are AdGuard DNS's DNS server addresses?

AdGuard DNS default: 94.140.14.14, 94.140.15.15, 2a10:50c0::ad1:ff, 2a10:50c0::ad2:ff. AdGuard DNS family protection: 94.140.14.15, 94.140.15.16, 2a10:50c0::bad1:ff, 2a10:50c0::bad2:ff. AdGuard DNS non-filtering: 94.140.14.140, 94.140.14.141, 2a10:50c0::1:ff, 2a10:50c0::2:ff.

Does AdGuard DNS validate DNSSEC?

Yes. On 2026-09-24 every AdGuard DNS address that answered returned SERVFAIL for three deliberately mis-signed domains while resolving ordinary names.

Does AdGuard DNS support DNS over HTTPS or DNS over TLS?

DoH: https://dns.adguard-dns.com/dns-query, https://family.adguard-dns.com/dns-query, https://unfiltered.adguard-dns.com/dns-query. DoT: dns.adguard-dns.com, family.adguard-dns.com, unfiltered.adguard-dns.com. 6 of 6 answered our test query on 2026-09-24.

Does AdGuard DNS send my IP subnet to other servers (ECS)?

Yes on at least one address: we observed a /24 client subnet reaching the authoritative server.

How can I check that I am using AdGuard DNS?

Run a DNS leak test and compare the network it reports with the one AdGuard DNS queried from in our probe (AS60068). On the command line, dig +short whoami.akamai.net @94.140.14.14 returns the address the resolver used to query Akamai.
