What is an IPv4 Subnet Calculator?

This advanced Subnet Calculator is a professional tool designed for network engineers, IT students, and system administrators. It allows you to quickly calculate CIDR notation, Subnet Masks, Network Addresses, Broadcast Addresses, and the usable host IP range.

How to use this tool:

  • Step 1: Enter an IPv4 address (e.g., 192.168.1.1).
  • Step 2: Select the Subnet Mask using the custom dropdown menu (CIDR /1 to /32).
  • Step 3: Click "Calculate" or press Enter.
  • Step 4: Use the "Interactive Binary Map" to visualize and toggle bits for educational purposes.

Key Features:

Unlike basic calculators, this tool provides a visual representation of the binary bits, helping you understand how the Network portion and Host portion of an IP address work. It also features automatic user simulation, history tracking, and export options for documentation.

Whether you are studying for your CCNA or managing a corporate network, this tool ensures accuracy in your subnetting tasks.
