The Emergence and Historical Role of Caching-Only DNS Servers in Traffic Management

As the Domain Name System (DNS) evolved to meet the growing demands of the internet, caching-only DNS servers emerged as a critical innovation in optimizing traffic management and improving the user experience. Unlike authoritative DNS servers, which store and provide definitive answers for specific domain records, caching-only servers do not host authoritative data. Instead, they…

The Emergence of DNS Cache Poisoning Attacks and Growing Awareness in the Mid-1990s

The Domain Name System (DNS), a cornerstone of internet functionality, was designed with simplicity and efficiency in mind. However, its early architects could not have foreseen the scale and complexity the internet would reach, nor the range of security threats it would face. Among these threats, DNS cache poisoning emerged as a particularly pernicious attack…

Tracing Root Server Attacks and Their Impact on DNS Security

The Domain Name System (DNS) operates as the backbone of the internet, enabling seamless translation of human-readable domain names into numerical IP addresses. At the core of this system lies the root zone, managed by 13 root server clusters distributed across the globe. These root servers play a critical role in directing DNS queries to…

The Historical Process of Expanding Top-Level Domains with Additions Like .info and .biz

The expansion of the Domain Name System (DNS) to include new top-level domains (TLDs) such as .info, .biz, and others marked a significant moment in the evolution of internet infrastructure. Originally, the DNS was organized around a small set of legacy TLDs, including .com, .org, .net, .edu, .gov, and .mil, which had been sufficient during…
