• - Generating IPv6 PTR records on the fly · ipv6 coredns · Thursday, August 29 2019
  In the IPv4 world doing a reverse DNS search should always return a PTR record. BIND has the ability to create such a zonefile by calling the $GENERATE function. With this you did not have to write each PTR record by hand. In IPv6 where a /56 contains 4.722.366.482.869.645.213.696 IPv6 addresses you are not able to store it in memory or in a file. The biggest ISP in germany is Deutsche Telekom and they provide a valid PTR for each IPv6 in their /23 network.
