By using the Subnet Calculator, you agree to be bound by these terms. This tool is provided for educational and network planning purposes.
While we strive for 100% accuracy in our IPv4 and IPv6 algorithms, network configurations can be complex. We recommend verifying critical network plans with secondary tools before implementation in live production environments.
We do not store the IP addresses or network prefixes you enter into this calculator. All calculations are processed on-the-fly. CSV and JSON exports are generated temporarily and are not saved on our servers.
The authors of this tool shall not be held liable for any network downtime, data loss, or configuration errors resulting from the use of the data provided by this calculator.
You are free to use this tool for both personal and professional networking tasks. Redistribution of the underlying code without permission is prohibited.
