My justification is that some sites may choose to communicate privately (i.e. not via the Internet) using their local addresses. Having these addresses in the global DNS (both forward and reverse) means that each site doesn't need to add its partners' zones to all of their name servers, which is rather error-prone. Also, if local addresses somehow leak into the Internet, having reverse entries in DNS may help trace the leak. Suggested text for 7.0: AAAA and PTR records for Local IPv6 addresses MAY be installed in the global DNS at the option of the site to which they are assigned. It is expected that most sites will not make use of this option, but some sites may find benefits in doing so. S Stephen Sprunk "Stupid people surround themselves with smart CCIE #3723 people.
