CloudFlare's 220.127.116.11 DNS service launched last year for desktops and laptops. We've been using it since launch, and it's rock-solid. The fastest public resolver, it's now available to speed up your mobile experience. For those unfamiliar, the Domain Name System, or DNS, works like a phone book for the Internet, resolving those easy-to-type addresses — like uncrate.com — into the IP addresses of their servers. 18.104.22.168 is built for speed, and as an added bonus prevents your carrier from tracking your browser history, which by itself is enough reason to use it.
