For IPv4 (most people), use the addresses 1.1.1.1 and 1.0.0.1

Android

You’ll have to use a static IP address to enable a custom DNS on Android, which is going to get complicated. Cloudflare recommends you configure your wireless router to use its DNS instead.
Pull up your router’s settings. (How you do that varies by what type of router you have; consult your router’s manual if you’re not sure how to do it.)

Replace any of its DNS settings with Cloudflare’s: 1.1.1.1 and 1.0.0.1 for IPv4 or 2606:4700:4700::1111 and 2606:4700:4700::1001 for IPv6.
Save your settings and restart your router
