What is an IP Subnet Calculator?

An IP Subnet Calculator is a tool that helps network administrators determine subnet masks, network addresses, broadcast addresses, and the number of available hosts in a network.

It is used for both IPv4 and IPv6 addressing to efficiently allocate IP addresses while avoiding wastage.

This calculator allows users to:

• Determine the network and broadcast addresses.
• Find the total number of usable hosts in a subnet.
• Calculate subnet masks based on network class (A, B, C) for IPv4.
• Analyze IPv6 networks with custom prefix lengths.

Using this tool, you can design networks efficiently while ensuring proper address allocation.
