According to The Hacker News (This article and its images were originally posted on The Hacker News January 10, 2019 at 03:40AM.)
Almost every activity on the Internet starts with a DNS query, a key function of the Internet that works as an Internet’s directory where your device looks up for the server IP addresses after you enter a human-readable web address (e.g., thehackernews.com).
Since DNS queries are sent in clear text over UDP or TCP without encryption, the information can reveal not only what websites an individual visits but is also vulnerable to spoofing attacks.
To address these problems, Google announced Wednesday that its Public DNS (Domain Name System) service finally supports DNS-over-TLS security protocol, which means that the DNS queries and responses will be communicated over TLS-encrypted TCP connections.
