CIDR Workbench is a focused subnet tool for network operators, students and engineers who need the calculation and the reasoning beside it. The first release handles IPv4 CIDR boundaries in the browser. It does not send entered addresses to a server.
Editorial standard
Every indexable tool must provide working utility, instructions, interpretation, a reviewed method, edge cases and source links. Planned features stay labelled as planned rather than being published as thin pages.
