IPv6 Compressor
Compress a standard IPv6 address into shorter canonical form. Useful for normalization, documentation, and network tooling.
Standard hexadecimal IPv6 only. This tool does not parse IPv4-embedded tails such as ::ffff:192.168.0.1.

How it works
This page validates a standard IPv6 address, expands it to eight 16-bit groups internally,
then compresses the longest run of zero groups using ::.
Examples
- 2001:0db8:0000:0000:0000:ff00:0042:8329 → 2001:db8::ff00:42:8329
- 0000:0000:0000:0000:0000:0000:0000:0001 → ::1
- fe80:0000:0000:0000:0202:b3ff:fe1e:8329 → fe80::202:b3ff:fe1e:8329

You can use this tool when handling simple tasks without installing additional software. The results should be interpreted as a processed output based on your input data.
FAQ
- What does this IPv6 compressor do?
It validates a standard IPv6 address and compresses it into a shorter canonical form using :: where appropriate.
- Does it support already compressed IPv6 input?
Yes. Valid IPv6 input can be normalized and returned in compressed form.
- Does it support IPv4-mapped IPv6 addresses?
No. This page focuses on standard hexadecimal IPv6 notation only and does not parse embedded IPv4 tails.
- Is my IP address stored?
No. Everything runs locally in your browser and no input is stored or transmitted.
