Explanation:

Here, we created a class Network that contains the Main() method. The Main() method is the entry point for the program.

In the Main() method, we created a string variable hostname then we get the hostname of the local machine using GetHostName() of Dns class. To use Dns class, we need to import System.Net and then print the hostname of the machine on the console screen.
