Output
version: IPv4 kind: ipv4-cidr address: 192.168.1.0 integer: 3232235776 hex: 0xc0a80100 binary: 0b11000000101010000000000100000000 octal: 0o30052000400 classification: private reverse-dns: 0.1.168.192.in-addr.arpa prefix: /24 netmask: 255.255.255.0 wildcard: 0.0.0.255 network: 192.168.1.0 broadcast: 192.168.1.255 addresses: 256 usable-hosts: 254 contains 192.168.1.10: yes
The result comes from deterministic local logic.
