IP Subnet Calculator — Accurate IPv4 & IPv6 Subnetting
Quickly calculate IPv4 and IPv6 subnets, including network address, broadcast address, host range, and CIDR notation. Essential tool for network planning and IT management.
What is an IP Subnet Calculator?
An IP Subnet Calculator is a tool that allows network administrators and IT professionals to divide an IP network into smaller, manageable sub-networks (subnets). It calculates:
- Network address
- Broadcast address
- Host range
- Subnet mask
- CIDR notation
- Number of usable hosts per subnet
Why Use an IP Subnet Calculator?
- Network Planning: Plan efficient IP address allocation for large networks.
- Reduce IP Wastage: Avoid assigning more addresses than needed.
- Ensure Security: Segment networks for improved isolation and security.
- Speed and Accuracy: Manual subnet calculations can be error-prone; a calculator ensures accuracy.
- IPv6 Support: Modern networks increasingly require IPv6 addressing.
How to Use the IP Subnet Calculator
Enter an IP address (IPv4 or IPv6) and subnet mask or prefix length. The tool will automatically calculate:
- Network Address
- Broadcast Address
- Range of Usable Hosts
- Number of Hosts
- CIDR Notation
