DNS servers are responsible for providing Domain Name System (DNS) services to computers on the network. DNS is a hierarchical system that maps domain names to IP addresses.

Computers use DNS to locate websites, e-mail addresses, and other resources by name.

DNS is essential for resolving hostnames to IP addresses. When a user types the name of a website, for example, the DNS server looks up the website’s IP address and returns the address to the user’s computer.

DNS also lets you configure your computer to automatically use the IP address of a specific website when you type its name into a web browser.

DNS also resolves e-mail addresses and other resource names. When you type the address of a website into your web browser, your computer looks up the website’s IP address and returns the address to your email program.

Your computer also uses DNS to resolve the name of a file on your hard drive to its corresponding file name.

DNS is an essential service for the Internet. Without DNS, users would have to know the IP addresses of all the websites and resources they want to access.

DNS also keeps the network running by resolving IP addresses for computers that can’t resolve them themselves.
