The Architectural Shield for Your Network.
AdAvoid DNS isn't just a filter. It's a high-velocity security layer that cleanses your digital environment before a single byte of unwanted data reaches your device.
What is DNS?
The Domain Name System translates human-readable domain names like example.com into IP addresses that computers use to connect. Every time you visit a website, your device sends a DNS query to resolve the address.
How Filtering Works
When you use our DNS, your queries go through our resolver instead of your ISP's default. We check every domain against curated filter lists before responding — blocked domains return a null address and never load.
The Filtering Process
Your device sends a DNS query (e.g. "resolve ad.tracker.com").
Our server checks the domain against the active filter lists for your chosen mode.
If the domain is on a blocklist, the server returns a null address (0.0.0.0) — the ad or tracker never loads.
If the domain is safe, the server resolves it normally and returns the real IP address.
Filtering Modes
Default
Blocks ads, trackers, and malware/phishing domains.
dns.adavoid.ioFamily
Blocks ads, trackers, malware, and adult content. Enforces safe search.
family.adavoid.ioUnfiltered
No blocking. Privacy-only encrypted DNS resolver.
unfiltered.adavoid.ioDNS filtering is best-effort and works at the domain-name level. False positives and false negatives can happen, and Family mode is not a complete parental-control compliance product. Read the Filtering Policy for details.
Built for Privacy, Not Profiles.
Unlike public DNS providers that monetize your browsing history, AdAvoid DNS does not keep user-identifying DNS query logs in normal operation. Read the full Privacy Policy.
No Browsing-History Logs
In normal operation, we do not keep user-identifying DNS query logs. Temporary local debug logs may be enabled only for specific operational investigations and deleted within seven days.
Encrypted Protocols
All queries are encrypted via DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC. Your ISP cannot see which domains you resolve.
No Data Selling
Your DNS query data is never sold, shared, or reported to third-party services. Period.
Open Standards
We strictly adhere to IETF standards, ensuring seamless compatibility with all modern operating systems and networking hardware.
