The browser sends a message, called a recursive DNS query, to the network to find out which IP or network address the domain corresponds to.The user enters a web address or domain name into a browser. The basic process of a DNS resolution follows these steps: This process of translation and lookup is called DNS resolution. They translate what a user types into a browser into something the machine can use to find a webpage. Most Uniform Resource Locators (URLs) are built around the domain name of the web server that takes client requests.ĭNS servers convert URLs and domain names into IP addresses that computers can understand and use. They also typically run DNS servers to manage the mapping of those names to those addresses. Access providers and enterprises, as well as governments, universities and other organizations, typically have their own assigned ranges of IP addresses and an assigned domain name. DNS mapping is distributed throughout the internet in a hierarchy of authority. Web browsing and most other internet activities rely on DNS to quickly provide the information necessary to connect users to remote hosts. An IP address is similar in structure to 203.0.113.72. The domain name system maps the name people use to locate a website to the IP address that a computer uses to locate that website.įor example, if someone types "" into a web browser, a server behind the scenes maps that name to the corresponding IP address. The domain name system (DNS) is a naming database in which internet domain names are located and translated into Internet Protocol (IP) addresses.
