Abstract: The Domain Name System (DNS) plays a crucial role in the functioning of the internet by translating human-readable domain names into machine-readable IP addresses, thereby enabling seamless connectivity across the globe. This paper delves into the operational mechanisms of DNS, including its hierarchical structure and various record types. It also highlights the challenges and vulnerabilities that DNS faces, such as DNS spoofing and DDoS attacks, and discusses the security measures implemented to mitigate these risks. The future of DNS, particularly with the integration of technologies like DNS over HTTPS (DoH) and IPv6, is explored to underscore its continued relevance in a rapidly evolving digital landscape.
