Each IPv4 address has 4 octets. The decimal value is: (octet1 × 2²⁴) + (octet2 × 2¹⁶) + (octet3 × 2⁸) + octet4. For 192.168.1.1: (192×16777216) + (168×65536) + (1×256) + 1 = 3,232,235,777.
Each octet is converted to a 2-digit hexadecimal number. 192.168.1.1 → C0.A8.01.01 → C0A80101. This format is often used in network device configurations and packet captures.
RFC 1918 defines three private ranges: 10.0.0.0/8 (10.x.x.x), 172.16.0.0/12 (172.16–31.x.x), and 192.168.0.0/16 (192.168.x.x). These are not routed on the public internet.
