Sorry, I have a confusing in the statement : "a query for a name that does not exist will yield the same response regardless of the reason why it is not in the zone. " A * label in zone record will response to a specified FQDN. Does a specified FQDN response is also means a non-existed name ? Or the * case is still in the meaning "the same response" ?
