IP Address to Binary Converter

Summary

This tool converts any valid IPv4 or IPv6 address into its binary representation, displaying each segment in 8-bit (IPv4) or 16-bit (IPv6) binary groups. It helps network engineers, students, and developers understand how IP addresses map to binary at the protocol level. The conversion is done entirely in your browser — no data is sent to any server.

How it works

1. Enter an IPv4 address (e.g. 192.168.1.1) or IPv6 address (e.g. 2001:db8::1) in the input field.
2. The tool automatically detects whether the address is IPv4 or IPv6.
3. Each octet (IPv4) or 16-bit group (IPv6) is converted to its binary equivalent.
4. Results are displayed with zero-padded binary segments separated by dots or colons.
5. Copy the full binary result or individual segments with one click.

Use cases

• Study subnetting and CIDR notation in networking courses.
• Debug network configurations by visualizing IP addresses in binary.
• Learn how subnet masks apply to IP addresses at the bit level.
• Verify binary representations when writing network scripts.
• Teach or demonstrate binary IP concepts in the classroom.
• Cross-check manual binary IP calculations instantly.
