>>191 そういう話もありましたね.ただ,未承諾さんがこういうのがあると
どこかで紹介してたような......

    Unlike DJB's rbldns, it has ability to specify individual values
    for every entry, can serve as many zones on a single IP address
    as you wish, and, finally, it is a real nameserver:
    it can reply to DNS metadata requests.
    The daemon keeps all zones in memory for faster operations,
    but its memory usage is very efficient, especially for
    repeated TXT values which are stored only once.

もし,これもいまいちだったら何か作ってみましょうという方向で......
