Web browsing and most other internet activity rely on DNS to quickly provide the information necessary to connect users to remote hosts. DNS mapping is distributed throughout the internet in a hierarchy of authority.
And enterprises, as well as governments, universities and other organizations, typically have their own assigned ranges of IP addresses and an assigned domain name; they also typically run DNS servers to manage the mapping of those names to those addresses. Most URLs are built around the domain name of the web server that takes requests.
For example, the URL for this page is techtarget.com/definition/domain-name-system. How does DNS work?DNS servers answer questions from both inside and outside their own domains. When a server receives a request from outside the domain for information about a name or address inside the domain, it provides the authoritative answer. When a server receives a request from inside its own domain for information about a name or address outside that domain, it passes the request out to another server - usually one managed by its. If that server does not know the answer or the authoritative source for the answer, it will reach out to the DNS servers for the top-level domain - e.g., for all of.com or.edu. Then, it will pass the request down to the authoritative server for the specific domain - e.g., techtarget.com or stkate.edu; the answer flows back along the same path. How does DNS increase web performance?To promote efficiency, servers can cache the answers they receive for a set amount of time.

The length of time the record is held - the - is configurable; longer values decrease the load on servers, shorter values ensure the most accurate responses.
