Instead of handpicking names or letting people insert data into your DNS
servers, some people are deploying PowerDNS with custom backends for
this that either convert the IPv6 address into a 128bit hex number,
optionally stripping the first 64 bits and replacing that with 'autogen'
or 'wlan-' or similar. Something else that I have seen is that the
backend randomly picks a name from a dictionary and then assigns that
'statically' to that address.

I wildcarded the subnets that we use for dynamic assignments. statically
assigned hosts get statically assigned reverse entries.
 
I personally only put hosts in reverse DNS that re-appear more than once.
