The Domain Name System (DNS) is a fundamental component of the internet’s infrastructure, serving as a crucial mechanism that translates human-friendly domain names into machine-readable IP addresses. This process is akin to a phonebook, where a domain name, such as www.example.com, can be transformed into a numerical identifier that computers use to communicate with each other over the internet. Understanding DNS is essential for grasping how the internet operates and for evaluating its performance.

At the core of DNS are domain names, which are organized in a hierarchical structure. Each domain name consists of several parts, with the top-level domain (TLD) being the last segment, such as .com or .org. Below the TLD are second-level domains, and further subdivisions can create subdomains. This structure ensures a systematic approach to addressing various resources across the internet.

In addition to domain names, DNS comprises various types of DNS records that store specific information regarding a domain. Some of the most common records include A records, which map domain names to IPv4 addresses; AAAA records for IPv6 addresses; CNAME records, which allow for aliasing one domain name to another; and MX records, which define mail exchange servers for email delivery. Each record type plays a distinct role within DNS evaluation, facilitating the seamless operation of web services.

DNS servers are another vital component of this system. They function as repositories for DNS records, handling queries from clients seeking to resolve domain names into IP addresses. These servers can be categorized into different types, including authoritative servers, which maintain complete data for specific zones, and recursive resolvers, which act as intermediaries that query multiple servers to provide a comprehensive response for client requests.
