How do I convert an IP address to binary?

Convert each of the four decimal octets (0-255) into its 8-bit binary equivalent, then join them with dots. This tool does the conversion automatically for any valid IPv4 address.

Why do IP addresses use binary at all?

Computers and network devices operate in binary at the hardware level. Decimal dotted notation exists purely for human readability.

What's the binary range for a single IP octet?

Each octet is 8 bits, giving a decimal range of 0 to 255, since 8 bits can represent 256 possible values (2^8).

Is hexadecimal used for IPv4 addresses in practice?

Hex is more commonly associated with IPv6 addressing, but converting IPv4 to hex is still useful for understanding number systems and low-level networking tasks.

Can this tool convert IPv6 addresses too?

This converter is focused on IPv4. For IPv6 interface IDs from a MAC address, use our free IPv6 to EUI-64 calculator.
