IPv4 Address Converter
Check an IPv4 address and see its exact dotted decimal, binary, hexadecimal, and unsigned integer representations instantly.
A QUICK WALKTHROUGH
How to use this tool
- Choose an input format and enter one IPv4 value.
- Select Convert and review the validation message.
- Copy any representation you need for networking, code, or documentation.
Four exact representations
Dotted decimal uses four octets from 0 through 255. Binary uses four 8-bit groups. Hexadecimal uses an optional 0x prefix and up to eight hexadecimal digits. The integer form is an unsigned value from 0 through 4,294,967,295.
Strict validation
The converter rejects missing groups, out-of-range octets, malformed digits, signs, fractions, separators, and values outside the 32-bit IPv4 range. Leading zeroes in decimal octets are accepted.
Local browser processing
Parsing, conversion, copying, and download preparation happen in your browser. The address is not sent to a server or used to perform a network request.
GOOD TO KNOW
Common questions
Does this look up the address?
No. It only validates and converts the text you enter; it never performs DNS, geolocation, or network requests.
Can I enter hexadecimal with 0x?
Yes. The 0x prefix is optional, and the value must contain one to eight hexadecimal digits.
Is the integer signed?
No. It is an unsigned 32-bit integer from 0 to 4,294,967,295.
Are binary groups required to be eight bits?
Yes. Binary input uses four groups separated by periods, with exactly eight 0 or 1 characters per group.
