IP Subnet Calculator

The IP Subnet Mask Calculator is a helpful networking tool that allows you to perform subnet calculations quickly and accurately. It helps you calculate subnet details using inputs such as network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets, and maximum required hosts per subnet.

This tool is designed for network administrators, students, IT professionals, and anyone who needs to plan or understand IP addressing and subnetting.

What Is an IP Subnet Mask Calculator?

An IP Subnet Mask Calculator is an online utility that calculates subnet information based on an IP address and related subnet parameters. Subnetting divides a large network into smaller, more manageable subnetworks, improving organization, performance, and security.

Instead of performing manual calculations, this tool provides instant and accurate results.

How Does the IP Subnet Mask Calculator Work?

The tool processes the information you provide, including:

• IP address
• Network class (A, B, or C)
• Subnet mask or mask bits
• Subnet bits
• Required number of subnets
• Required number of hosts per subnet

Using these inputs, the calculator determines subnet ranges, usable IP addresses, broadcast addresses, and other essential subnet details.

How to Use the IP Subnet Mask Calculator

Using this tool is simple:

1. Select IP Version (IPv4 or IPv6)
2. Enter the IP address
3. Enter Subnet Mask or CIDR as required
4. Click the Calculate button
5. View the calculated subnet results

The results are displayed in a clear, easy-to-understand format.
