TOOL
IP Address Converter
Convert an IPv4 address between dotted-decimal, integer, hex and binary. Enter any form.
Processing happens locally in your browser. Nothing you type is sent to BlackhawkHub.
How to use it
Enter an IPv4 address in any of four forms and see all of them:
- Dotted decimal:
192.168.1.37 - Integer: the 32-bit value,
3232235813 - Hexadecimal:
0xC0A80125 - Binary:
11000000.10101000.00000001.00100101
The tool detects which form you typed. The binary view shows why subnet masks and CIDR work the way they do: the mask marks which leading bits belong to the network. For non-address numbers, the Number Base Converter handles arbitrary hex, decimal and binary.
Frequently asked questions
What is an IP address as a decimal number?
An IPv4 address is a 32-bit number, so it can be written as a single integer from 0 to 4,294,967,295. 192.168.1.1 is 3,232,235,777. Some systems and databases store addresses this way.
Why convert an IP to binary?
To see the network and host bits directly, which is how subnet masks and CIDR prefixes work. The binary view makes subnetting intuitive.
