  `0`s, and IPv4-mapped IPv6 values (e.g. `::ffff:192.168.0.1`) are forbidden.
  These sorts of values can potentially cause security problems when different
  components interpret the same string as referring to different IP addresses
  (as in CVE-2021-29923).
  
  This tightening applies only to fields in built-in API kinds, and not to

    * `kubectl set selector` and `kubectl set subject` no longer print "running in local/dry-run mode..." at the top.  The output can now be piped and interpretted as yaml or json ([#46507](https://github.com/kubernetes/kubernetes/pull/46507), [@bboreham](https://github.com/bboreham))

  Kubernetes will keep allowing leading zeros on IPv4 address to not break the compatibility.
  IMPORTANT: Kubernetes interprets leading zeros on IPv4 addresses as decimal, users must not rely on parser alignment to not being impacted by the associated security advisory:
