What task does the DNS system perform in a network?

The DNS (Domain Name System) is responsible for converting human-readable domain names (e.g., example.com) into IP addresses (e.g., 93.184.216.34), which are used for routing traffic on the network.

The main task of DNS is to make it easier for users to access resources on the internet by hiding complex numerical addresses behind understandable names. When you enter a website address in your browser, the request is first sent to a DNS server, which returns the corresponding IP address.

Example:

• The user enters google.com in the browser
• The computer contacts the DNS server
• The DNS server returns an IP address, for example, 142.250.190.78
• The browser establishes a connection with this IP

Without DNS, it would be necessary to remember and enter IP addresses directly, which is inconvenient and impractical.
