Prefixloom performs deterministic IPv4 capacity planning from recorded inputs; it does not discover live devices, reserve addresses, configure routers, or replace authoritative IPAM. Verify overlap, routing, DHCP, VRFs, security zones, cloud reservations, and current assignments before deployment.

Get it. Prefixloom: Subnet Planner is on the App Store for iPhone and iPad.
