In the digital age, privacy is paramount. As internet usage grows, so do concerns about data security and privacy. Two emerging technologies aimed at enhancing DNS privacy are DNS over TLS (DoT) and DNS over HTTPS (DoH). This blog post explores what these technologies are, how they work, and why they are crucial for protecting online privacy.

Understanding DNS and Its Privacy Issues

Before diving into DoT and DoH, it’s essential to understand the Domain Name System (DNS). DNS is the internet’s phonebook, translating human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network. However, traditional DNS queries are sent in plaintext, making them susceptible to eavesdropping and man-in-the-middle attacks. This lack of encryption allows third parties to monitor, log, and potentially manipulate DNS traffic, posing significant privacy and security risks.

The function of a Private DNS server

A Private DNS server appears to be something unique, as the name suggests. It creates a connection between your network and the Domain Name System server, preventing unauthorized access to data. These DNS networks are separate from the Public DNS. Think of it as a little private library with a selection of books. There are benefits and drawbacks to this. You will indeed be unable to read several genres of literature. However, there is one benefit: since your library is private, no one will know what you are reading.

Additionally, DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure) are terms we use to refer to Private. This is due to the fact that all DNS queries are encrypted when using DoT (DNS over TLS) or DoH (DNS over HTTPS). This makes it much harder for nefarious third parties to watch your online behavior.
