Re: Reverse DNS for IPv6 client networks

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.
