What is MATRIX?
MATRIX is a set of address and transfer calculators for network design and operations. It brings together subnet checks, address allocation, CIDR aggregation, ACL masks and packet sizing.
The tools are free and require no account. Calculations run in your browser; IP addresses, address lists and file sizes are not sent to a calculation server or saved as a calculation history.

Methods and limitations
Each tool includes its method, examples, assumptions and relevant standards. Address calculations do not validate device routing, firewall policies or special-purpose address restrictions. Check device documentation and your environment before making changes.
Operation and advertising
Advertising may help support the service in the future. Ads are labeled and separated from calculator inputs, outputs and actions. Advertising does not influence calculation results.
