Those in the security space may already be aware of the secure DNS service provided by Quad9. For those who have not heard of this free service, Quad9 is a public Domain Name System (DNS) service that provides a more secure and privacy-focused alternative to traditional DNS services. DNS is the system that translates human-readable domain names (like www.google.com) into IP addresses that computers use to identify each other on the internet.
Quad9 is known for its emphasis on security and privacy. It uses threat intelligence from various cybersecurity companies to block access to known malicious websites and protect users from accessing harmful content. When a user makes a DNS query, Quad9 checks the requested domain against a threat intelligence feed, and if the domain is flagged as malicious, Quad9 blocks access to it.
One notable feature of Quad9 is its commitment to user privacy. Quad9 does not store any personally identifiable information about its users, and it does not sell or share user data.
Users can configure their devices or routers to use Quad9 as their DNS resolver to take advantage of its security and privacy features. The DNS server addresses for Quad9 are usually 220.127.116.11 and 18.104.22.168.
The name “Quad9” is derived from the service’s use of four DNS servers in different geographic locations to provide redundancy and improve reliability. Users can configure their devices or routers to use the Quad9 DNS servers, and doing so can offer an additional layer of protection against malware, phishing, and other online threats. It’s important to note that while Quad9 can enhance security, it is not a substitute for other security measures such as antivirus software and good internet security practices, and if you are not using these technologies already, then you are leaving yourself open to compromise.
I’d strongly recommend you take a look at Quad9. Not only is it fast, but it seems to be extremely solid, and well thought out. If you’re using Cloudflare for your DNS, Quad9 is actually faster.
