How It Works
Each of the four octets in an IPv4 address is an 8-bit number (0–255). Converting to binary means expressing each octet in base 2, padded to 8 digits. This underlies every subnetting calculation — subnet masks, network boundaries, and wildcard masks are all binary operations under the hood.
