Rndc reconfig gave the following error: 22-May-2017 07:58:13.534 general: error: reloading configuration failed: already exists This was the entirety of the error message. > If you don't want A to AAAA mappings to happen then turn off the > DNS64 mapping for everyone on the server. > dns64 2001:67c:2b0:db32:0:1::/96 { > clients { none; } > }; When I removed the empty master zone, the error message went away. So it seems that the dns64 declaration implicitly creates a new zone in Bind. Makes sense. This could be added to documentation? I think the above error message should also be improved, as it gave no indication as to *what* exists already. I could have saved about an hour of wondering what the hell is wrong with my config change, if the error message was a bit more wordy. :-) In hind sight, I guess I could have turned on debugging and seen what messages would be generated then, but I suspect there would have been too many messages for me to process. Anyway, thanks for the help. -- Aleksi Suhonen / Axu TM Oy Internetworking Consulting Cellular: +358 44 975 6548 World Wide Web: www.axu.tm _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
