The Domain Name System (DNS) has long been a cornerstone of the internet, enabling users to access online resources by translating human-readable domain names into numerical IP addresses. While its original design prioritized functionality and scalability, the system’s trust model was largely implicit, lacking robust mechanisms to ensure the authenticity and integrity of DNS responses.…

The evolution of the Domain Name System (DNS) has been closely intertwined with the internet’s growth and the increasing demand for secure and private communication. One of the most significant developments in this history is the integration of DNS with virtual private network (VPN) services, which marked a pivotal shift toward secure remote resolution of…

The rise of streaming services like Netflix, YouTube, and others has fundamentally reshaped the internet, driving unprecedented demand for bandwidth, low latency, and reliable content delivery. These platforms, which rely on the seamless transmission of high-quality video and audio content to millions of users worldwide, have exerted a profound influence on the strategies and architecture…

The 2007 DNS root distributed denial-of-service (DDoS) attack marked a significant moment in the history of internet security, highlighting both the vulnerabilities and resilience of the Domain Name System (DNS). This attack, targeting the very core of the DNS infrastructure—the root servers—underscored the critical role these servers play in ensuring global connectivity and demonstrated the…

The adoption of IPv6 within the Domain Name System (DNS) represents one of the most significant yet gradual transformations in internet history. IPv6, designed as the successor to IPv4, introduced an expanded address space to accommodate the exponential growth of connected devices and alleviate the exhaustion of IPv4 addresses. DNS, as the system responsible for…

The Domain Name System (DNS), as the backbone of internet navigation, has played a central role in debates around net neutrality. Net neutrality, the principle that all internet traffic should be treated equally, free from discriminatory practices like blocking, throttling, or paid prioritization, has sparked contentious policy discussions and legal battles worldwide. DNS, by its…

DNS Blacklists (DNSBLs) have played a pivotal role in the fight against email spam, leveraging the capabilities of the Domain Name System (DNS) to provide a scalable and efficient solution to a problem that has plagued the internet since its earliest days. These blacklists, which use DNS queries to identify and block known sources of…

The Domain Name System (DNS) is a fundamental component of the internet’s infrastructure, originally designed to provide a scalable, efficient mechanism for mapping human-readable domain names to numerical IP addresses. While its creators envisioned DNS as a tool to enhance usability and connectivity, the system’s evolution into a multi-billion-dollar industry has fundamentally reshaped the internet…

DNS over HTTPS (DoH) represents a transformative shift in the way Domain Name System (DNS) queries are transmitted and resolved, aiming to enhance user privacy and security by encrypting DNS traffic. Emerging in the late 2010s, DoH was a response to growing concerns about the vulnerability of traditional DNS to surveillance, tampering, and exploitation. Its…

DNS blocking and filtering have been among the most prominent tools for internet censorship since the early days of the Domain Name System (DNS). As the internet expanded and became a powerful medium for communication, commerce, and information sharing, governments, organizations, and other entities sought ways to control access to specific online content. DNS, as…
