🌐 IP Range Calculator CIDR
Introduction
CIDR (Classless Inter-Domain Routing) helps organize IP addresses efficiently by defining networks with variable-length subnet masks. The IP Range Calculator CIDR allows you to quickly find the usable IP address range within any CIDR block, making network planning and management straightforward.
Why Use an IP Range Calculator CIDR?
Calculating IP ranges from CIDR notation manually can be complex. This tool enables you to:
- ✅ Instantly determine the first and last usable IP addresses within a CIDR block
- 📊 Calculate network and broadcast addresses
- 🧠 Understand subnet size and number of hosts
- 🔍 Verify network allocations accurately
- 🚀 Save time and reduce configuration errors
Perfect for network engineers, IT professionals, and students.
How It Works
Input:
- IP Address (IPv4)
- CIDR Notation (e.g., /24)
The calculator outputs:
- Network Address
- Broadcast Address
- First Usable IP Address
- Last Usable IP Address
- Total Number of Usable Hosts
- Subnet Mask (decimal and binary)
Example
- IP Address: 192.168.1.10
- CIDR: /28
Results:
- Network Address: 192.168.1.0
- Broadcast Address: 192.168.1.15
- Usable IP Range: 192.168.1.1 – 192.168.1.14
- Total Usable Hosts: 14
