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.
- 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)
- No client subnet reached the authoritative server from any address we probed.
- Plain DNS and NXDOMAIN
- 12/12 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.

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.
| ASN | Holder | Role |
|---|---|---|
| AS398962 | CONTROLD - CONTROLD INC. | Announces the service addresses |
| AS212238 | CDNEXT Datacamp Limited | Queried from, in our probe |
Confirm your device is using Control D Free 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.
# Which address did the resolver query from?
dig +short whoami.akamai.net @76.76.2.0
# Does it pass your subnet on (ECS)?
dig +short TXT o-o.myaddr.l.google.com @76.76.2.0
# Does it validate DNSSEC? SERVFAIL means yes
dig dnssec-failed.org @76.76.2.0Behind 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.

- Does Control D Free DNS validate DNSSEC?
- Yes. On 2026-09-24 every Control D Free DNS address that answered returned SERVFAIL for three deliberately mis-signed domains while resolving ordinary names.
- Does Control D Free DNS support DNS over HTTPS or DNS over TLS?
- DoH: https://freedns.controld.com/p0, https://freedns.controld.com/p1, https://freedns.controld.com/p2, https://freedns.controld.com/p3, https://freedns.controld.com/family, https://freedns.controld.com/uncensored. DoT: p0.freedns.controld.com, p1.freedns.controld.com, p2.freedns.controld.com, p3.freedns.controld.com, family.freedns.controld.com, uncensored.freedns.controld.com. 11 of 12 answered our test query on 2026-09-24.
- Does Control D Free DNS send my IP subnet to other servers (ECS)?
- We observed no client subnet on any address we probed.
- How can I check that I am using Control D Free DNS?
- Run a DNS leak test and compare the network it reports with the one Control D Free DNS queried from in our probe (AS212238). On the command line, dig +short whoami.akamai.net @76.76.2.0 returns the address the resolver used to query Akamai.
