ℹ️ About IP Address Inventory Tool
The IP Address Inventory Tool is a fundamental planning utility for system administrators and network architects. Before deploying new services or configuring hardware, you must have a clear understanding of your IP address space. This tool takes any CIDR range and provides a comprehensive breakdown of its technical properties.
By calculating the total and usable IP addresses, identifying the network and broadcast boundaries, and providing the netmask and wildcard masks, this tool simplifies the inventory process. It's an essential first step for managing IP Address Management (IPAM) spreadsheets or configuring DHCP scopes and static assignments in a professional environment.
📖 How to use IP Address Inventory Tool
- 1. Enter the network range using CIDR notation (e.g., <code>192.168.1.0/24</code> or <code>10.0.0.0/8</code>).
- 2. Click 'Run Tool' to calculate the inventory details.
- 3. Review the 'Usable Range' to know which IP addresses you can assign to devices.
- 4. Use the 'Netmask' and 'Broadcast' values when configuring your routers and servers.
❓ Frequently Asked Questions
What is CIDR notation?
CIDR (Classless Inter-Domain Routing) is a compact way to represent an IP address and its associated routing prefix (e.g., /24 means a subnet mask of 255.255.255.0).
Why are there 2 fewer 'Usable' IPs than 'Total'?
In any subnet, the first address is the Network ID and the last address is the Broadcast address. These cannot be assigned to individual hosts.
Does this tool track real-time IP usage?
No. This is a calculator for planning and inventory purposes. For real-time tracking, you would need a dedicated IPAM system or a network scanner.
