When you enter a web address into your browser, a series of technical processes execute to establish a connection to the requested website. The Domain Name System (DNS) serves as a critical component in this process, functioning as a distributed directory service that converts human-readable domain names into machine-readable IP addresses. DNS operates as the internet’s addressing system, enabling seamless navigation between websites without requiring users to memorize numerical IP addresses.
Each time you access a website, your device initiates a DNS query to resolve the domain name into its corresponding IP address. This process involves multiple DNS servers working in hierarchy, from local DNS caches to authoritative name servers, to provide the accurate IP address needed for connection establishment. DNS configuration directly affects internet performance and security.
Internet Service Providers typically assign default DNS servers to users, but these may not offer optimal speed or security features. Users can modify their DNS settings to improve browsing performance, reduce latency, and enhance security through features such as malware blocking and content filtering.
