    There is no such thing as a dangerous, evil IP. There are such things as
    malicious users (human or otherwise) using computers connected to the
    internet which have an IP address.

    These things are spread out all over the place. The Bogon list at
    cymru.com is a good list of IP addresses to filter out on your edge
    router.

    cymru tracks unassigned IP blocks. Maintaining a list of IP space which
    has been allocated to RIRs but not to LIRs, is harder. Maintaining a
    list of dark IP space in blocks allocated to end user is next to
    impossible.

    I would recommend using the list at Cymru as a filter, but trying to get
    more fine grained than that is not recommended.
