IPv6 Address Expander / Compressor

IPv6 Address Expander / Compressor

Expand compressed IPv6 addresses to full 128-bit notation, or compress expanded addresses to their shortest valid form following RFC 5952 canonical rules. Validate, convert, and inspect IPv6 addresses — all client-side.

Comment utiliser

Enter an IPv6 address in any format — compressed (2001:db8::1) or expanded. The tool instantly shows the expanded form, compressed form, binary representation, and decimal integer. Compression rules are explained so you can see exactly what changed. Use batch mode for multiple addresses.
