DoT and DoH: Enhancing DNS Privacy
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.
