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 such as, for example, the IP 126.96.36.199 on Globo.

The solution, in this case, is to use a reliable alternative such as Google's public DNS.
