Compression rules

How IPv6 compression works

  1. 1Leading zeroes are removed from every four-character hexadecimal group.
  2. 2The longest sequence of two or more 0000 groups can be replaced once with ::.
  3. 3Hexadecimal letters are written in lowercase for a consistent canonical form.

Zero-group analysis

The expanded address contains a longest uninterrupted sequence of 3 zero groups. That sequence is eligible for the :: abbreviation.

Compressed notation is useful in configuration files, logs, command output, and URLs. It represents exactly the same 128-bit address as the expanded form.
