What this trail covers

Cloudflare launched 1.1.1.1, a consumer-facing DNS service focused on speed and privacy. This service aims to address the inherent privacy and censorship issues of traditional DNS resolvers by offering faster lookups and a commitment to not logging user data. The service leverages Cloudflare's global network for performance and was made possible through a collaboration with APNIC for IP address allocation. The launch also included accompanying mobile applications for iOS and Android.
