How DNS servers work
DNS servers basically works like this: every time you type a search or domain name of a website into your browser, your machine follow a series of steps in order for it to convert your request into an IP address that allows you to access certain websites , And this happens every time you wish to stream online content, send email or check the website.
When you type in a search term or a domain name into your browser, the first thing your device to do is look at the DNS cache (which acts as a store for all DNS information devices you have searched and inquired in the past) to see if it's there. Otherwise, the device will put fresh DNS request, based on your search terms or domain name, go out to the web and bring you a response.

Traditionally, DNS queries and replies are sent in plain text. However, it does have the advantage of allowing the Security Operations Center (SOC) team overseeing a larger, enterprise networks can easily monitor the domain in question and block users from accessing malicious websites. So even though they are plain text DNS requests is less personal they provided valuable intelligence for them oversee the security of the network.
How could the same loss of visibility of security lacking
But now, with the introduction of the DoH and DNS requests are encrypted via HTTPS protocol, communication can be more easily malware disguised as normal HTTPS traffic, making it more difficult to detect.
The irony will not be lost on you - DNS encryption via HTTPS strengthen some protection but actually weakens the others!
