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 Does not validate
Returned addresses for dnssec-failed.org, rhybar.cz and badsig.go.dnscheck.tools, which a validating resolver would refuse. Tested over the encrypted endpoint.
Client subnet (ECS)
Not measured: this probe used plain DNS, which the operator does not offer publicly.
Plain DNS and NXDOMAIN
The operator documents encrypted service only.

“We use OpenNIC as our Tier 1.”
Check it
Confirm your device is using LibreDNS
From a terminal
# Which address did the resolver query from?
dig +short whoami.akamai.net @116.202.176.26
# Does it pass your subnet on (ECS)?
dig +short TXT o-o.myaddr.l.google.com @116.202.176.26
# Does it validate DNSSEC? SERVFAIL means yes
dig dnssec-failed.org @116.202.176.26Behind 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
LibreDNS questions
What are LibreDNS's DNS server addresses?
LibreDNS: 116.202.176.26, 2a01:4f8:1c0c:8274::1.
Does LibreDNS validate DNSSEC?
Not in our 2026-09-24 test: it returned addresses for all three deliberately mis-signed domains.
Does LibreDNS support DNS over HTTPS or DNS over TLS?
DoH: https://doh.libredns.gr/dns-query. DoT: dot.libredns.gr. 2 of 2 answered our test query on 2026-09-24.
How can I check that I am using LibreDNS?
Run a DNS leak test and compare the network it reports. On the command line, dig +short whoami.akamai.net @116.202.176.26 returns the address the resolver used to query Akamai.
