Explanation of the Code:

This Python script is designed to perform a network port scan on a range of IP addresses and ports. It checks for open ports on specified IP addresses and generates a report in JSON format detailing the open ports found.

User Instructions:

---

Running the Script:

Ensure you have Python installed on your system.

Save the script to a file, for example, deranged-port-scanner.py.

Open a terminal or command prompt and navigate to the directory containing the script.

Run the script by typing python deranged-port-scanner.py and press Enter.

Input Instructions:

Base IP Address: Enter the base part of the IP address (e.g., 192.168.1.). Do not include the last part (the number).

Start and End IP Numbers: Enter the range of IP numbers you want to scan. For example, if your base IP is 192.168.1., entering 1 and 10 will scan from 192.168.1.1 to 192.168.1.10.

Start and End Port Numbers: Enter the range of ports you want to scan. Ports range from 1 to 65535.

Output:

The script will log its activities in the terminal.

If any open ports are found, a report file named report.json will be created in the same directory as the script, detailing the open ports for each IP address.

Error Handling:

The script includes error handling for invalid IP addresses, incorrect IP ranges, and invalid port ranges. If an error occurs, it will log the error message and stop execution.
