To run the application, execute the following command:

python src/main.py

The application will perform the following steps:

1. For each hostname or IP provided the range of ports provided will be scanned
2. Printing results will be in a simple tabular format
3. Print order isn't guranteed
4. Unresolvable hosts will be silently skipped

If the Python version is less than 3.11, the user will be prompted for confirmation before proceeding.
