Domain Name System (DNS) servers are used to map Internet addresses to corresponding human-readable names. When a user types an address into a web browser, the browser contacts a DNS server to look up the address and return the corresponding name.

DNS servers are also used to provide name resolution for services such as email, instant messaging, and file sharing. When a user types an email address into a web browser, the browser contacts a DNS server to look up the address and return the corresponding email address.

DNS servers are also used to map hostnames to IP addresses. When a user types a hostname such as “www.

google.com” into a web browser, the browser contacts a DNS server to look up the hostname and return the corresponding IP address.

DNS servers are essential for the operation of the Internet. Without DNS servers, users would not be able to access websites or email addresses that they know.
