1. IP Structure

An IP address is like a phone number. It has a Network part (Area Code) and a Host part (User Number).

2. The Slider (/CIDR)

The slider controls the "Slash Notation". Moving it right increases the Network bits (Green) but leaves fewer bits for Hosts (Red).

3. Visualizer

Look at the "Block Visualizer" below the binary. It shows how the network is sliced into smaller chunks as you change the mask.
