About this tool
Convert any IPv4 address to binary, hexadecimal, octal and decimal-integer forms — and back again.
The IPv4 Converter is a network utility that translates IPv4 addresses between their four-octet dotted-decimal representation (192.168.1.1) and equivalent integer, hexadecimal, and binary formats instantly. It's essential for network engineers, security analysts, and backend developers working with firewall rules, IP-based access control, subnet calculations, and log analysis where IP addresses appear in different formats.
Enter any valid IPv4 address and the converter displays its decimal integer value (used in databases and CIDR calculations), hexadecimal representation (common in network headers), and full 32-bit binary form (for subnet mask analysis). The conversion is bidirectional — enter an integer, hex value, or binary string to get the corresponding dotted-decimal address.
For security teams correlating IP logs across systems, developers building IP-based access control lists, and network engineers analyzing packet captures, this tool provides instant format conversion without CLI tools or custom scripts. All conversions are client-side — your IP addresses and network topology details remain on your machine.
