How IPv6 expansion works
- 1An IPv6 address always has eight 16-bit hexadecimal groups.
- 2Each visible group is left-padded with zeroes until it contains four digits.
- 3If :: appears, it is replaced with the number of 0000 groups needed to reach eight groups.
Binary representation
128 bits, grouped for inspection
Each block below represents one 16-bit IPv6 group. This form is useful when comparing prefix bits or troubleshooting subnet boundaries.
