🌐 Range of IP Addresses Calculator
Introduction
Knowing the exact range of IP addresses within a subnet is vital for effective network management. The Range of IP Addresses Calculator helps you quickly find the start and end IP addresses of any subnet, making IP allocation and troubleshooting easier.
Why Use a Range of IP Addresses Calculator?
Manually calculating IP ranges can be tricky and error-prone. This tool allows you to:
- ✅ Instantly find the first and last usable IP addresses in a subnet
- 📊 Determine network and broadcast addresses
- 🧠 Convert subnet masks between decimal and CIDR formats
- 🔍 Verify network segments for proper IP allocation
- 🚀 Save time and minimize errors in network configuration
Perfect for network engineers, IT professionals, and students.
How It Works
Input:
- IP Address (IPv4)
- Subnet Mask or CIDR Notation (e.g., 255.255.255.0 or /24)
The calculator outputs:
- Network Address
- Broadcast Address
- First Usable IP Address
- Last Usable IP Address
- Total Number of Usable IPs
Example
- IP Address: 192.168.100.50
- Subnet Mask: 255.255.255.192 (or /26)
Results:
- Network Address: 192.168.100.0
- Broadcast Address: 192.168.100.63
- Usable IP Range: 192.168.100.1 – 192.168.100.62
- Total Usable IPs: 62
