i.e., it's configuring to be authoritative for the same 8 RFC1918 address ranges, twice, and ignoring the others. As expected given the syslog, it's not returning any results for lookups to 168.192.in-addr.arpa. Is this something I'm doing wrong, or is it genuinely misconfiguring itself, despite the options it was invoked with? How can I troubleshoot this further?
