Introduction
In the rapidly growing digital landscape of Asia, understanding and managing DNS (Domain Name System) is crucial for businesses aiming to establish a robust online presence. DNS is the backbone of the internet, translating human-friendly domain names into IP addresses that computers use to identify each other on the network. As such, proficient DNS management is vital for ensuring seamless connectivity and accessibility to web resources. With Asia’s digital transformation accelerating at an unprecedented rate, the demand for skilled professionals who can set up, manage, and secure DNS servers has never been higher.
