InetAddress.getLocalHost()

In Java, `InetAddress.getLocalHost()` is a method that returns an instance of the `InetAddress` class representing the local host. It essentially returns the IP address of the machine on which the code is running.

Here's an example:

import java.net.InetAddress;
import java.net.UnknownHostException;

public class LocalHostExample {
    public static void main(String[] args) {
        try {
            InetAddress localhost = InetAddress.getLocalHost();
            System.out.println("Localhost IP Address: " + localhost.getHostAddress());
            System.out.println("Localhost Host Name: " + localhost.getHostName());
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
}

When you run this code, it will print out the IP address and host name of the local machine. Note that `getHostName()` may not always return the fully qualified domain name (FQDN) of the machine, depending on the configuration.
