DNS Over HTTPS

DNS over HTTPS (DoH) is a protocol that encrypts Domain Name System (DNS) traffic between a client and a DNS resolver, providing increased security and privacy for DNS queries. By encrypting DNS traffic, DoH prevents eavesdropping and man-in-the-middle attacks, making it more difficult for attackers to intercept and manipulate DNS responses.

Why Learn DNS over HTTPS?

There are several reasons why individuals may want to learn about DNS over HTTPS:

• Enhanced Security: DoH provides a secure channel for DNS queries, reducing the risk of eavesdropping and data interception.

• Improved Privacy: DoH prevents Internet Service Providers (ISPs) and other entities from tracking users' DNS queries, protecting their browsing history and online behavior.

• Increased Performance: DoH can improve the performance of DNS lookups by reducing latency and resolving DNS issues related to caching and spoofing.

• Compliance with Regulations: Some organizations and industries have regulations that require the use of secure DNS protocols like DoH to ensure the confidentiality and integrity of their DNS traffic.

• Growing Adoption: DoH is gaining widespread adoption in web browsers, operating systems, and DNS resolvers, making it essential for individuals to understand its benefits and implementation.
