Features and specs

What each product offers, as listed by its team.

Quad9 5 features
YieldStack 2 features
  • Privacy-Focused
    Quad9 does not store any personal data about users and maintains a stringent privacy policy, ensuring that your DNS queries are not tracked or sold to third parties.
  • Security
    Quad9 provides robust security features by blocking access to known malicious domains, which helps protect users from phishing, malware, and other online threats.
  • Performance
    With a global network of servers, Quad9 offers fast DNS resolution, which can contribute to quicker website load times and improved overall internet browsing experience.
  • Easy to Set Up
    Changing your DNS to Quad9 is straightforward and can be easily configured on most devices without requiring technical expertise.
  • Free Service
    Quad9 offers its DNS services free of charge, making it an accessible option for anyone looking to improve their online privacy and security without additional costs.

Possible disadvantages

  • Limited Customization
    Quad9 does not offer as many customization options as some competing services, which may be a drawback for advanced users looking for more control over their DNS settings.
  • Possible Geolocation Issues
    Using a global DNS resolver like Quad9 can sometimes lead to geolocation issues, where content or services are delivered based on server location rather than user location.
  • Not as Established
    Quad9 is a relatively new entrant in the DNS space compared to longstanding providers like Google Public DNS and OpenDNS, which might make some users hesitant.
  • Dependency on Upstream Filters
    Quad9's security filtering relies on upstream threat intelligence providers. Therefore, the comprehensiveness of the protection is dependent on the accuracy and timeliness of these third-party sources.
  • Unverified: possible specialization
    I can't browse yieldstack.ai and have no reliable information about this product, so I can't confirm its features. If it is a focused tool in the yield or optimization space, a narrow focus can mean a simpler, more purpose-built experience than a general-purpose platform. Check the site to confirm what it does.
  • Unverified: possible AI-driven automation
    The .ai domain suggests AI or automation features, which could save time on analysis or decisions if they work as advertised. This is an inference from the domain name, not a confirmed feature. Verify it against the product's documentation or demo.
