Google’s public DNS: how to improve the Internet on Windows and macOS

0

Google’s public DNS is a free solution that can be used on Windows PCs or macOS to improve the Internet. The DNS (Domain Name System) is the bridge that is responsible for translating the IPs of the sites into friendly addresses – like, for example, the IP 186.192.90.5 on Globo.com. This service is provided by Internet operators, but the servers are not always good, and may fail and prevent access to websites or be slow. The solution, in this case, is to use a reliable alternative such as Google’s public DNS.

In the following tutorial, check out how to change your computer’s DNS address and use Google DNS. The walkthrough shows how to perform the procedure on PCs with Windows 10 and also on the Mac. In the latter, the images were captured on macOS Catalina, but the tips also apply to other versions of the Apple system.
