Every IPv4 address is fundamentally a 32-bit number. The familiar dotted notation (like 192.168.1.1) is just a human-readable way of presenting four 8-bit octets. Databases, routing tables, and network APIs often store or compare IP addresses as plain integers because integer comparisons are faster and more memory-efficient than string comparisons.
To convert an IPv4 address to a decimal integer, each octet is multiplied by its positional weight: - First octet × 16,777,216 (2²⁴) - Second octet × 65,536 (2¹⁶) - Third octet × 256 (2⁸) - Fourth octet × 1
For example, 192.168.1.1: - 192 × 16,777,216 = 3,221,225,472 - 168 × 65,536 = 11,010,048 - 1 × 256 = 256 - 1 × 1 = 1 Total: 3,232,235,777
