As seen in the verbose logs, every 15 minutes (the default), If the zone is nonsecure or set to "none " and the record does NOT exist, at step 3, DNS will create the DNS record (A(host) and PTR). **Note – Due to modern DNS client cache, the momentary delete / recreate of the DNS record is not noticed by clients.
