IP to Binary, Decimal & Hex Converter

How it works

1. 1

   Enter an address

   Type an IPv4 address in any form: dotted quad, dotted binary, a 32-bit binary string, a decimal integer or hex.

2. 2

   Read every form

   See the dotted binary, the 32-bit decimal integer and the hex value side by side, with a row for each octet.

3. 3

   Convert back

   Paste a binary, integer or hex value and the converter shows the matching dotted-quad address.

Frequently asked questions

How do I convert an IP address to binary?

Convert each of the four octets to an 8-bit binary number and join them with dots. 192 is 11000000, 168 is 10101000, so 192.168.0.1 becomes 11000000.10101000.00000000.00000001. The converter shows the binary for every octet so you can check the bit pattern.

What is the decimal integer form of an IP address?

An IPv4 address is 32 bits, so it can be written as a single unsigned integer from 0 to 4294967295. You build it by treating the four octets as the four bytes of that integer. 192.168.0.1 is 3232235521. This form is handy for storing addresses in code or a database.

Can I convert binary, integer or hex back to an IP?

Yes. Paste any of those forms into the input and the converter detects it and shows the dotted-quad address. It reads dotted binary, a 32-bit binary string, a decimal integer in range, and hex with or without a 0x prefix.

Does the conversion happen on a server?

No. Everything runs in your browser, so the address you enter is never sent anywhere. The converter keeps working once the page has loaded and is safe to use with internal addresses.
