⚠️ Subnet Range Explanation：
• Network Address: First address of the subnet
• Broadcast Address: Last address of the subnet
• Available IP Range: Network address + 1 to broadcast address - 1
• Total Addresses: 2^(32-CIDR)
• Network Address: First address of the subnet
• Broadcast Address: Last address of the subnet
• Available IP Range: Network address + 1 to broadcast address - 1
• Total Addresses: 2^(32-CIDR)
