    Non-authorative are answers that came from a naming service that is NOT responsible for the domain "website.com". This implies that it may be not accurate, out of date or worse. But they are generally fine since they are used to speed up ns resolutions. A possible threat is "DNS cache poisoning". You can look that up for reference and more information.
