Domain Name System

Definition ∞ The Domain Name System, commonly known as DNS, is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It translates human-readable domain names, such as example.com, into numerical IP addresses that computers use to identify each other. DNS functions as the internet’s phonebook, making it possible for users to access websites and send emails using memorable names. This system is foundational to how the internet operates.
Context ∞ While traditionally centralized, news in the digital asset space increasingly explores decentralized alternatives to the conventional Domain Name System, such as blockchain-based naming services. These decentralized solutions aim to offer censorship resistance and enhanced security, preventing single points of control or failure. The ongoing evolution of DNS infrastructure holds implications for website accessibility and digital identity management in a Web3 future.
