Why this tool is useful
Use this converter when a database, binary protocol or log stores IPv4 addresses as integers and you need an exact human-readable cross-check without signed 32-bit surprises.

IPv4 Address Number Converter
Convert a strict dotted IPv4 address to unsigned decimal, hexadecimal and 32-bit binary, or turn an unsigned integer back into dotted notation.
Ready. Your working data stays in this browser.
How it works
Address mode shifts four validated octets into one unsigned 32-bit value; number mode accepts only canonical decimal or 0x hexadecimal values from zero through 4294967295.
Practical example
192.0.2.1 maps to decimal 3221225985, hexadecimal 0xC0000201 and the corresponding 32-bit binary string.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
