    My understanding is that this will work with BINDv9 since the cache
    synthesizes all responses returned to the requestor and a bad response
    wouldn't be synthesized.  BINDv8 and BINDv4 will sometimes (in an attempt to
    be faster) simply pass the authoritative response on to the requestor (which
    is the bad thing).  Don't have a clue about what dnscache or MS DNS would
    do.
