If the query reaches the authoritative server and it cannot find the information, it returns an error message.The next time it receives a request for that domain name, it can respond directly to the user instead of querying other servers. The recursive server stores, or caches, the A record for the domain name, which contains the IP address.DNS root name servers and TLD servers primarily redirect queries and rarely provide the resolution themselves. It sends this information to the recursive DNS server, and the webpage the user is looking for loads. The three server types work together and continue redirecting until they retrieve a DNS record that contains the queried IP address.

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.
