An IP Subnet Calculator is a handy tool that helps you break down IP address ranges into smaller subnetworks. Whether you're managing a home lab or designing an enterprise network, subnetting is key to organizing and securing your IP space.
Just enter an IP address and subnet mask (or CIDR prefix), and the calculator instantly gives you details like the network address, broadcast address, and the range of usable IPs.
This tool supports IPv4, making it useful for planing your network or next VLAN.
