Quad9 DNS

Free Quad9 DNS Service Combats Cyber Fraud


Now there is another tool to help protect us from the thieves, cons and ne’er-do-wells on the Internet. IBM Security, Packet Clearing House, and the Global Cyber Alliance recently launched a free service designed to give consumers and businesses added privacy and security protection as they access the internet. The new Quad9 DNS service helps protects users from accessing millions of malicious internet sites known to steal personal information, infect users with ransomware and malware, or conduct fraudulent activity.

Con Artists Are Everywhere On The Internet

Like con artists, these attackers prey on our greed, vanity, and even our grief and compassion to gain our trust so they can carry out their nefarious deeds. Even the most tech-savvy of us can fall for a well-crafted con. It seems they come at us from everywhere with spoofed email addresses, fake download buttons, and disguised links in social media posts.

There are many ways Internet companies and organizations try to protect us from these schemes. Spam filtering and anti-spoofing technology have been around for awhile protecting us from dangerous email. And of course, antivirus software can alert us to viruses and malware. Website security certificates can warn us about websites’ real owners. Recently, browsers like Google Chrome have been warning us if we are about to visit a fraudulent website.

But most of these methods are only deployed after the con has already begun. Often after the enemy is already behind many of our lines of defense. That’s what makes the Quad9 DNS service so different. It stops the attack from launching in the first place. 

Quad9 DNS Service is engineered for privacy

The Quad9 DNS service also protects your privacy. It is engineered to not store, correlate or otherwise leverage any personally identifiable information. In contrast, other DNS services often capture Information about the websites you visit, devices you use and where you live for marketing or other purposes. 

How The Quad9 DNS Service Works

The Domain Name System is how your computer maps DNS names like www.websitename.com to IP addresses. Whenever a Quad9 user clicks on a website link or types an address into a web browser, Quad9 checks the site against a threat intelligence database. If it finds the address it blocks your computer from connecting with it. 

Quad9 checks websites against IBM X-Force’s threat intelligence database of over 40 billion analyzed web pages and images. The service also taps feeds from 18 additional threat intelligence partners including Abuse.ch, the Anti-Phishing Working Group, Bambenek Consulting, F-Secure, mnemonic, 360Netlab, Hybrid Analysis GmbH, Proofpoint, RiskIQ, and ThreatSTOP.

Quad9 protections are not limited to traditional PCs and laptops. The service also protects other internet connected devices like smart TVs and the ever-growing number of Internet of Things (IoT) technologies such as smart thermostats and connected home appliances. These devices often do not receive important security updates and are also difficult to secure with traditional anti-virus tools, but remain connected to the internet leaving them vulnerable to hackers.

How to configure Quad9 DNS service

Quad9 offers step by step instructions with screenshots and two easy to follow videos that will show you how to configure your PC or Mac to use Quad9 DNS servers ( 

Of course, you can also configure your Internet router to use Quad9 DNS servers so all of your computers will automatically use them when they get their settings from DHCP. See your router’s documentation to set its DNS server to Quad9’s ( 

Quad9 DNS server performance

Quad9 was built so you shouldn’t sacrifice any speed while using it. In my own testing, Quad9 DNS servers can resolve IP addresses within a few milliseconds of my ISP DNS servers and is often faster than Google DNS servers  ( DNS makes up only a small fraction of the overall time it takes to download a web page. You can test the speed your DNS server with the Google namebench utility or the freeware utility DNS Benchmark.
