Every website lives at a numerical IP address. Your Domain Name Server, or DNS, translates these numerical IP addresses into readable domain names 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 cybercrime and performance issues.
Quad9 is a free security solution that uses DNS to protect your system against the most common cyber threats. It takes less than 5 minutes to implement; it only requires that you change your DNS settings to 220.127.116.11. 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.
