128-bit binary, eight 16-bit groups separated by colons.
Expand any IPv6 address into its 128 binary bits. Useful when studying IPv6 prefix structure, designing routing exercises, or validating subnet boundaries.
Why is the binary so long?
IPv6 addresses are 128 bits — four times longer than IPv4 — to provide a vastly larger address space.
Can I use shorthand like ::1?
Yes. Compressed IPv6 forms are accepted and expanded into all eight groups before conversion.
Does the reverse direction shorten output with ::?
No. The reverse mapping returns the full eight-group form so you can inspect every group explicitly.
