Google’s Public DNS works with Android 9 Pie
Google's Public DNS now works with Android 9 Pie – By Corbin Davenport, www.androidpolice.com
A Domain Name System, or DNS for short, is the component of your network connection that looks up the server IPs after you enter a domain name (e.g. androidpolice.com). Most people use the default DNS services from their ISPs/carriers, but alternatives have existed for years, like Google Public DNS. Google announced today that its DNS service finally supports DNS-over-TLS, meaning it can be set as the system-wide DNS provider on Android 9 Pie.
When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS.
