DNS is a hierarchical system that translates human-readable names like “www.example.

com” into the numerical IP addresses used by computers. DNS is typically hosted by a domain name registrar, such as GoDaddy, or by a hosting provider, such as Amazon Web Services.

DNS is critical for hosting websites and other Internet services. It allows users to access websites by entering their address into a web browser, rather than remembering a long string of numerical IP addresses.

DNS is also used to resolve domain names into the corresponding IP addresses. For example, if someone types the domain name “example.com” into a web browser, DNS will look up the IP address for “www.

example.com.”.

DNS is a distributed system, meaning that it is not hosted by a single organization. Instead, it is hosted by a number of different organizations, each of which is responsible for a specific part of the system.

This is why DNS can be slow or unavailable sometimes.
