Every website lives at a numerical IP address. Your Domain Name Server, or DNS, translates these numerical IP addresses into readable domain names (like google.com or facebook.com) we all know and remember. If your DNS settings are not working correctly, or you’re still using defaults, you may be at risk for cyber crime and performance issues.
Quad9 is a free security solution that uses DNS to protect your system against the most common cyber threats. It takes 5 minutes to implement; you change your DNS settings to use 18.104.22.168. It improves your system’s performance, plus, it preserves and protects your privacy. It’s like an immunization for your computer. See the Quad9 website for more information.
