How it works
An IPv4 address is four numbers from 0 to 255. Leading zeros are flagged because some systems read them as octal. With CIDR notation (/24), the tool computes the subnet mask, network and broadcast addresses and the usable host range. Address types follow the IANA special-purpose registry: private (10/8, 172.16/12, 192.168/16), loopback, link-local, carrier-grade NAT, multicast, documentation and reserved ranges.
