Android Pie supports Private DNS, which uses DNS over TLS to secure your queries. If your device runs Android 9, this is the recommended method to set up 188.8.131.52 because unlike previous versions of Android, it does not need to be configured for each new WiFi network.
Follow these steps to configure your device to use 184.108.40.206.
Step 1: Go to Settings → Network & internet → Advanced → Private DNS.
Step 2: Select the Private DNS provider hostname option.
Step 3: Enter
1dot1dot1dot1.cloudflare-dns.com and hit Save.
