IP to Binary Converter
Convert IPv4 addresses to dotted binary and back, with hex and 32-bit integer forms.
See an IP address bit by bit
An IPv4 address is a 32-bit number written as four dot-separated parts (octets). Seeing an address in binary is the best way to understand how subnet masks work and where the network and host parts split.
Conversions
- Dotted decimal → dotted binary: 192.168.1.1 → 11000000.10101000.00000001.00000001
- Binary → dotted decimal
- Hexadecimal and 32-bit integer equivalents
- Address type (private, public, loopback, multicast, etc.)
Ideal for students
Practise subnetting for CCNA, Network+ and university networking courses by converting addresses to binary.

Why use this tool?
Makes network concepts easier to learn by visualising them, and speeds up low-level networking work.
FAQ
Can I paste 32 bits without dots?
Yes. A 32-character string of 0s and 1s is split into four octets automatically.
Why store IP addresses as integers?
Databases can query and sort IP ranges faster when addresses are stored as 32-bit integers.
What is the maximum value of an octet?
Each octet is 8 bits and ranges from 0 to 255.
