It is a critical component of the internet infrastructure, enabling users to access websites by typing in human-readable domain names rather than numerical IP addresses. DNS works by maintaining a distributed database of domain names and their corresponding IP addresses, which is then queried by clients to resolve domain names to IP addresses. The system operates on a hierarchical structure, with multiple levels of name servers that work together to provide accurate and efficient DNS resolution. DNS plays a vital role in web browsing, email delivery, and other internet-based services, making it an indispensable part of the internet's functionality.
