Binary → IPv4

Convert a valid 32-bit binary value to standard IPv4, with each binary octet and its decimal value shown side by side.

Enter 32 continuous bits, four dot-separated groups, or groups separated by spaces or line breaks.

Validate exactly 32 binary digits, then convert continuous, dotted, or whitespace-grouped binary input to IPv4.

Your input is processed only in your browser and is never uploaded to a server.

What this tool does

Binary to IPv4 accepts 32 continuous bits, four dotted 8-bit groups, or binary input grouped with spaces and line breaks. It never silently removes invalid characters; after permitted whitespace separators are removed, exactly 32 zeros and ones must remain.

  • Dotted input must contain exactly four 8-bit groups.
  • Undotted input can use spaces or line breaks for grouping.
  • A clear error appears if the input contains 2, letters, or other unsupported symbols.

How to use it

  1. Paste a supported 32-bit binary format.
  2. Click Convert to IPv4.
  3. View the Binary to Decimal table for all four groups.
  4. Copy the final dotted-decimal address.

How it works

After validation, the 32 bits are split in order into four 8-bit octets. Each group is converted by binary place value to a decimal number from 0 to 255, then joined with dots as A.B.C.D.

Examples

  • 11000000101010000000000100000001 → 192.168.1.1.
  • 11000000 10101000 00000001 00000001 → 192.168.1.1.
  • An input with 31 bits, 33 bits, or the character 2 → Invalid binary IPv4.

Common uses

  • Convert a 32-bit value from a packet capture or protocol document back to IPv4.
  • Verify the decimal value of each binary octet.
  • Cross-check conversions in both directions with IPv4 to Binary.

Privacy

Inputs and results are processed only in local browser memory. Nothing is uploaded, sent to an online API, or stored automatically.

Binary → IPv4 Features

Validate exactly 32 binary digits, then convert continuous, dotted, or whitespace-grouped binary input to IPv4. Useful for network planning, configuration checks, and troubleshooting; results can be reviewed and copied immediately.

FAQ

Which separators are supported?

Periods, spaces, and line breaks are supported. Without periods, whitespace may appear between any groups of bits.

Why must the input contain exactly 32 bits?

IPv4 has a fixed width of 32 bits. One extra or missing bit cannot represent a complete address.

Are invalid characters ignored automatically?

No. Any character other than 0, 1, or a permitted separator causes an error.

Is the result sent to a server?

No. Validation and base conversion take place entirely in your browser.
