Subnet Calculator

Subnetting is the process of dividing a larger network into smaller subnetworks. It's a fundamental concept in networking that allows for more efficient use of IP addresses and improved network performance and security.

Key Concepts:

• Network Address: The first address in a subnet, used to identify the network itself.
• Broadcast Address: The last address in a subnet, used to send data to all devices on the subnet.
• Subnet Mask: Determines which part of an IP address refers to the network and which part refers to the host.
• CIDR Notation: A compact way to specify the subnet mask (e.g., /24 for 255.255.255.0).
• Usable Hosts: The number of addresses that can be assigned to devices, excluding the network and broadcast addresses.
