Transparent mathematical methodology explained in plain English.
Network = IP AND Mask | Broadcast = Network OR (~Mask) Applies bitwise binary AND and OR logic to 32-bit IPv4 addresses to segment networks and identify host boundaries.
Variables Explained:
- CIDR: Prefix length indicating number of network bits (e.g., /24).
- Usable Hosts: 2^(32 - CIDR) - 2 (subtracting network and broadcast addresses).

Network breakdown.
Sample Project Inputs:
IP Address: 192.168.1.50
Prefix: /26
Step-by-Step Calculation:
- Subnet mask: 255.255.255.192 (64 address block).
- Network address: 192.168.1.0.
- First usable host: 192.168.1.1.
- Last usable host: 192.168.1.62.
- Broadcast address: 192.168.1.63.
- Total usable hosts: 62.
Calculated Answer: Network: 192.168.1.0/26 with 62 usable host addresses.

Why are two addresses subtracted from total hosts?
In traditional IPv4 networking, the all-zeros host address is reserved for the network identifier, and the all-ones host address is reserved for local broadcast.
