As technology continues to evolve, ensuring the security and privacy of your online activities becomes increasingly important. One way to enhance your web browsing experience is through DNS over HTTPS setup. This protocol encrypts your DNS queries, safeguarding your browsing data from prying eyes and potential threats. In this article, we will explore the fundamentals of DNS over HTTPS, its advantages, and provide a detailed guide on how to set it up on various devices and browsers.

1. What is DNS over HTTPS?

To understand the significance of DNS over HTTPS, let’s first recap what DNS (Domain Name System) is. DNS acts as the internet’s phonebook, translating human-friendly domain names into IP addresses that computers use to identify each other on the network. However, traditional DNS queries are sent in plain text, making them susceptible to eavesdropping and tampering by malicious actors.

DNS over HTTPS (DoH) remedies this vulnerability by encrypting DNS queries through the HTTPS protocol. This not only ensures that your DNS traffic remains private but also prevents third parties from intercepting or modifying your requests. Consequently, this enhances overall web security and user privacy.
