Free community DNS resolvers you can use without an account.
TL;DR
Control D offers free, public DNS resolver endpoints you can use without needing an account. They let you resolve domain names with built-in filtering (optional) and encryption, backed by our global anycast network.
Why We Offer Them
To let anyone benefit from faster, safer DNS without signing up
To showcase our filtering in “open mode”
To help folks who don’t want the overhead of managing a full account or dashboard
To let devs / power users test configurations easily
What They Do / Don’t Do
What They Do
Resolve DNS queries (map domain names to IPs)
Support encrypted DNS (DoH, DoT, QUIC)
Optionally block domains according to curated Native and 3rd-party blocklists (ads, malware, tracking, etc.)
Refresh those blocklists periodically (every 30 minutes) so filters stay current
Operate over an anycast infrastructure to reduce latency and improve reliability
Not store logs (no individual browsing history, timestamps, or query logs)
What They Don’t Do
They are not a full dashboard / profile management system
You cannot create custom rules or fine-tune individual domains (beyond what the blocklists provide)
They don’t provide analytics or reporting
If you want custom Filters or per-device profiles, that’s in the paid offering
How They’re Structured
We expose multiple blocklist presets as distinct resolver endpoints. Each flavor corresponds to one or more blocklists. You pick whichever fits your needs:
