📖 IP Subnetting

Subnetting divides IP networks into smaller segments. CIDR notation (like /24) specifies how many bits are used for the network address.

🔧 Calculated Values

• Network and broadcast addresses
• First and last usable hosts
• Subnet and wildcard masks
• Total and usable host count

💡 Tips

→ /24 = 256 addresses (254 usable)
→ Private ranges: 10.x, 172.16-31.x, 192.168.x
