But before you decide to use that feaure you should step back and ask
yourself a couple of questions:

Do I need global IPv6 addresses on the link?  It's not required, so if
you don't actually need it for anything then just don't bother
allocating any.

Should the prefix I assign to the customer's LAN (presumably by
DHCPv6-PD) be dynamically allocated? People have different opinions
here.  There isn't a right or wrong answer.  But the question should be
asked, since the number of available addresses means that you *can*
allocate a static prefix for every end user site.

Personally I hate renumbering, and can't understand why I should force
that on innocent users :-)
