I need this many Usable IPs (Auto-calculates CIDR)

                        Total IPs
                            ?
                            All IPs in the generated range, including the reserved Network and Broadcast addresses.
                        
                        256
                    

                        Usable IPs
                            ?
                            The actual number of IPs you can assign to host devices (Total minus 2).
