Guide
Convert an IPv4 address to dotted binary and plain 32-bit binary notation online.
IPv4 addresses are usually written in dotted decimal notation, such as 192.168.1.1. Underneath that familiar format, each address is a 32-bit value split into four 8-bit parts. This converter shows the binary representation for each part and also provides the full 32-bit string.
Binary IP conversion is useful when learning subnetting, checking masks, studying routing behavior, or debugging low-level network documentation. Seeing each octet as eight bits makes it easier to understand how address ranges, network prefixes, and host portions are calculated.
The tool validates that the input has four parts and that each part is from 0 to 255. It then pads each binary octet to eight characters so the output stays aligned. That padding is important because 1 is written as 00000001 inside an IPv4 address.
Use this page when you need a quick conversion without opening a command line or spreadsheet. It is especially helpful for study notes, networking tutorials, firewall planning, and explaining how a dotted decimal address maps to binary.
Quick reference
192.168.1.1
Binary: 11000000.10101000.00000001.00000001 / Plain: 11000000101010000000000100000001
IPv4 addresses are 32-bit values split into four octets. Hex and binary outputs are alternate views of the same value.
Hex pairs and binary octets are padded so each address part keeps its byte-level shape in documentation and debugging notes.
These tools do not parse IPv6 or mixed notation. Keeping IPv4 pages focused reduces ambiguous results.
Common mistakes
IPv4 has four 8-bit octets. Each decimal part becomes one binary group.
Each IPv4 octet must be shown as eight bits, so smaller numbers are padded with leading zeros.
No. This page is focused on IPv4 addresses.
