On Sunday, 11/11, Cloudflare released their 1.1.1.1 DNS app for iOS and Android. Significantly, this app not only points any iOS device's DNS to 1.1.1.1 (and 1.0.0.1 for backup), it also encapsulates them inside either an HTTPS or TLS tunnel, thus completely hiding them from anyone who might be passively snooping on the user's DNS queries.
