Enter an IPv4 address and this tool shows it in binary, broken into its four eight bit octets so the structure stays readable. It also gives you the full 32 bit binary string, the hexadecimal form and the plain integer value, so you can see the same address expressed four ways at once. Reading an IP in binary is the clearest way to understand how subnet masks split an address into a network part and a host part, which makes this a great learning aid as well as a quick reference. Each octet is padded to eight digits so the columns line up and it is easy to spot which bits are set. There is no rounding or ambiguity here, just an exact bit level view. All of the conversion happens locally in your browser, so the address you type is never sent to a server or logged.
