    I don't think Team Cymru offers a "feed" of what is supposed to be in
    the routing table. 128/1 isn't a bogon. It's not even that useful
    for hijacking adress space.

    The correct approach would be to verify prefixes using somewhat
    indepedent. more static data, such as RPSL data from RIRs. The old
    blacklist vs. whitelist discussoin. (I know that creating a useful
    whitelist is a huge tsak.)
