The Domain Name System (DNS) is a critical component of the internet, translating human-readable domain names into the numerical IP addresses that computers use to communicate. Despite its importance, the original design of DNS lacked robust security mechanisms, leaving it vulnerable to attacks such as cache poisoning, spoofing, and man-in-the-middle intrusions. To address these vulnerabilities,…

The Domain Name System (DNS) serves as the internet’s directory, mapping domain names to their corresponding IP addresses. Among its many features, DNS supports wildcard records, a mechanism that allows administrators to create generalized responses for undefined subdomains within a domain. While DNS wildcard records offer significant technical advantages, their implementation introduces a range of…

The Domain Name System (DNS) serves as a critical enabler of internet connectivity, allowing users to access information and services through human-readable domain names. Beyond its technical functionality, DNS has the potential to play a vital role in public health campaigns and emergency alert systems, serving as a platform for the dissemination of timely, accurate,…

The Domain Name System (DNS) serves as the backbone of internet functionality, enabling the resolution of domain names into IP addresses and facilitating seamless connectivity. Over time, as the internet has grown in scale and complexity, challenges in maintaining and upgrading the DNS have become increasingly evident. To address these issues, the concept of DNS…

The Domain Name System (DNS) is the foundation of the internet’s navigation, and its governance involves a complex interplay of technical standards, operational practices, and policy decisions. Two of the most influential bodies in DNS governance are the Internet Corporation for Assigned Names and Numbers (ICANN) and the Internet Engineering Task Force (IETF). Both organizations…

DNS Security Extensions (DNSSEC) provide a crucial layer of security for the Domain Name System (DNS) by enabling cryptographic authentication of DNS responses. This prevents tampering and ensures that users receive accurate and trusted information. A core aspect of DNSSEC implementation is the choice of cryptographic algorithms used for signing and validating DNS records. The…

The Domain Name System (DNS) underpins the functionality of the internet, enabling users to navigate the web by resolving human-readable domain names into machine-readable IP addresses. However, the same system that facilitates global connectivity is often exploited for malicious purposes. DNS abuse, which includes activities such as phishing, malware distribution, botnet command-and-control, and DNS-based amplification…

The Domain Name System (DNS) has evolved significantly since its inception, adapting to meet the demands of a rapidly growing and changing internet. Over the next decade, DNS policy will continue to evolve, shaped by emerging technologies, evolving threats, and the need to balance competing priorities such as privacy, security, accessibility, and governance. Understanding the…

The Domain Name System (DNS) is an essential component of the internet’s architecture, translating human-readable domain names into machine-readable IP addresses that direct traffic to websites and online services. Beyond its technical function, the DNS has also become a powerful tool for implementing regulatory and policy objectives, including the enforcement of content restrictions, protection against…

The Domain Name System (DNS) operates as the backbone of the internet, facilitating the seamless resolution of domain names into IP addresses. Central to the allocation and management of these IP addresses are Regional Internet Registries (RIRs), which oversee the distribution of internet number resources within specific geographic regions. While RIRs primarily focus on IP…
