Frequently Asked Questions
Why convert an IP to binary?
Converting an IPv4 address to its 32-bit binary form is fundamental to understanding networking concepts like subnetting. Network devices operate at the binary level, so seeing the address in this format helps visualize how subnet masks work to separate network and host portions.
