- Hosts needed should include the gateway and any addresses reserved for routers or HA pairs.
- Every subnet starts on a multiple of its own size, as routing requires.

Technische Hinweise auf Englisch
IPv4 only, up to 200 subnets. Subnets that do not fit are listed as such rather than overlapping. Everything is calculated in your browser; nothing is sent or probed on the network.
Each subnet gets the smallest prefix whose usable addresses cover its hosts. Largest subnets are placed first, each aligned on a multiple of its own size, so no address is wasted between them. The remaining space is summarised as CIDR blocks.
192.168.0.0/22 split for 250, 120, 60, 50, 25 and 2 hosts gives /24, /25, /26, /26, /27 and /30 with 476 addresses left.
