DNS over HTTPS

explained

When you navigate to a website, your browser first needs to determine which server is responsible for delivering said website, a step known as DNS resolution. For most people, their system automatically uses their Internet Service Provider's DNS. Users can configure their system to use 3rd party DNS if they so desire, such as Google's 8.8.8.8 public DNS server. In a small office or larger corporate network, it is common that DNS resolution is handled by the firewall or a special purpose dedicated DNS server for the LAN. This is part of the network security layer and the network administrator likely prefers or enforces all DNS queries be handled locally.

Mozilla Firefox (the group responsible) and Google Chrome via The Chromium Project are now implementing something called DNS over HTTPS. They claim this is to provide an encrypted channel which they say further safeguard user security and privacy.
