      public static String canonize(String ipv6Address) throws IllegalArgumentException

      Convert IPv6 address into RFC 5952 form. E.g. 2001:db8:0:1:0:0:0:1 -> 2001:db8:0:1::1

      Method is null safe, and if IPv4 address or host name is passed to the method it is returned without any processing.

      Method also supports IPv4 in IPv6 (e.g. 0:0:0:0:0:ffff: -> ::ffff:, and zone ID (e.g. fe80:0:0:0:f0f0:c0c0:1919:1234%4 -> fe80::f0f0:c0c0:1919:1234%4).

      The behaviour of this method is undefined if an invalid IPv6 address is passed in as input.

      ipv6Address - String representing valid IPv6 address.
      String representing IPv6 in canonical form.
      IllegalArgumentException - if IPv6 format is unacceptable.
