What is DNS over TLS, and how should you test it?

We’ve mentioned CloudFlare’s 1.1.1.1 DNS Service before, and the possible effects of its use on gateways. One of its features is the ability to use DNS over TLS, also called “DNS Privacy” by the people at DNSPrivacy.org.

Wifi is unique in that it is a complex networking system that users are aware of, and make purchasing decisions for consumer electronics and for broadband service around it.
