Bear in mind that that reverse populating your IPv6 space in entirety is
potentially going to hurt you (the $GENERATE command actually generates
an RR for each record which will be held in the zone in memory).  Think
about how many records your $GENERATE is going to create.  You don't
want to have named failing to start because it does not have enough
memory (or the machine on which it is running does not have enough
memory) to hold all of the PTR RRsets in the zone.

Please also think about whether you need to do this or not, especially
as the names are going to follow a generic pattern and not provide any
useful intelligence about the host using that address.

Instead, I would suggest that you just create PTR entries for the IPv6
hosts that actually need them for some reason, or to use dynamic DNS to
add/replace/delete them as addresses are used/discarded by dynamic clients.
