## What the models said for it

- "For better privacy without logging concerns, services like Quad9, NextDNS (with logging disabled), and Mullvad DNS are generally recommended" (Claude Haiku 4.5, DNS filtering)
- "Quad9 (`9.9.9.9`) is a Swiss-based non-profit that blocks malicious domains, does not log IP addresses, and supports DoH/DoT." (Gemini 3.5 Flash, DNS filtering)
- "Consider these alternatives instead: Quad9 (non-profit, strong privacy, malware blocking)" (Kimi K2, DNS filtering)
- "Prefer non-profit or privacy-focused providers - Quad9 and similar" (MiniMax M2.5, DNS filtering)

## And against it

- "Avoid free/public options (e.g., Quad9, OpenDNS basic) for B2B" (Grok 4.20, DNS filtering)
- "Quad9 is oriented toward malicious-domain blocking... neither should be treated as a substitute for endpoint protection." (Perplexity Sonar, DNS filtering)
- "considered to be a single-purpose, non-scalable resolver that is not suitable as a primary enterprise filtering service" (Llama 4 Maverick, DNS filtering)
- "it’s usually not the best fit for a mid-sized B2B company that wants enterprise policy control and growth into SSE" (GPT-5.4 mini, DNS filtering)
