How IPv6 expansion works

  1. 1An IPv6 address always has eight 16-bit hexadecimal groups.
  2. 2Each visible group is left-padded with zeroes until it contains four digits.
  3. 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.
