Domain Names

The domain name system, often known as DNS, is a database that stores names and is used to locate and translate domain names on the internet into Internet Protocol (IP) addresses. The Internet Protocol address (IP address) that a computer uses to locate a website is mapped to the human-readable name of the website via the domain name system (DNS).

If someone were to input “example.com” into a web browser, for instance, a server would automatically map that name to the appropriate IP address. An Internet Protocol address has a format that is analogous to 203.0.113.72.

Web browsing, along with the vast majority of other internet activities, is dependent on DNS to supply the information required to link users to remote hosts in a timely manner. The mapping of DNS is decentralised over the internet and organised in a hierarchy of authorities. Access providers and businesses, in addition to governments, universities, and other organisations, generally have their own allotted ranges of IP addresses and a domain name that is specific to them. In addition to this, they usually operate DNS servers so that they may handle the mapping of those names to those addresses. The majority of Uniform Resource Locators (URLs) are constructed around the domain name of the web server that is responsible for handling client requests.
