Instructions:

Each time you click "Next Problem" (or reload the page) a random IP address and CIDR value is generated.

You are then tasked to solve the Network ID, Broadcast IP, First Host IP, Last Host IP, and Next Network addresses for the target IP.

Options:

You get the same, if not better, visual clarity as a massive 30GB to 40GB original Blu-ray rip, but compressed into a much more manageable 2GB to 4GB file.
