Industrial Network Subnet Calculator

Plan an IPv4 subnet and verify the network, broadcast, mask, wildcard, usable host range, and address classification before changing PLC, HMI, drive, or switch settings.

Subnet Calculator

Calculate network, broadcast, usable host range, subnet mask, wildcard mask, and binary octets.

Before applying an address change

Check the actual VLAN, gateway, routing, duplicate-IP risk, PLC I/O tree, HMI shortcuts, managed-switch configuration, and documented recovery path.

Supporting knowledge-base guides

Start with a public worked example, then use the complete Pro procedure for commissioning and troubleshooting.
