What is a 32-bit binary IP address?

IPv4 addresses are 32-bit numbers. They are usually written in dotted-decimal notation (e.g. 192.168.1.1), but each octet is really an 8-bit binary number. So 192 = 11000000, 168 = 10101000, and so on.

Does this tool support IPv6?

No. IPv6 uses 128-bit addresses. This tool is specifically for 32-bit IPv4 addresses. An IPv6 converter would need to handle hexadecimal groups rather than binary octets.

Can I enter the binary with spaces or dots?

Yes. The tool strips all spaces and dots before parsing, so 11000000.10101000.00000001.00000001 and 11000000 10101000 00000001 00000001 and 11000000101010000000000100000001 are all equivalent inputs.

Why does each octet need exactly 8 bits?

Each of the four octets in an IPv4 address holds a value from 0 to 255, which requires exactly 8 binary digits. A full IPv4 address is therefore 4 × 8 = 32 bits.

What happens if I enter fewer than 32 bits?

The tool will show an error asking for exactly 32 binary digits. You can pad leading zeros if an octet starts with 0 (e.g. 00001010 for 10).

Summary

This tool converts a 32-bit binary string (e.g. 11000000101010000000000100000001) to its dotted-decimal IPv4 equivalent (e.g. 192.168.1.1), and back. It also shows the per-octet breakdown so you can follow every step of the conversion. Everything runs entirely in your browser with no data sent to any server.

How it works

Choose the conversion direction: Binary to IP or IP to Binary.
Enter a 32-bit binary string (spaces and dots are accepted) or a valid IPv4 address.
The result appears immediately below with a per-octet breakdown table.
Use the Copy button to copy the output to your clipboard.
Click Swap to reverse the conversion direction in one click.
