    http://www.pch.net/routing-origin-inconsistency/

     From the help page: "This tool identifies inconsistencies between
    the autonomous systems which the Regional Internet Registries believe
    are authoritative origins for routing announcements of each IP address
    prefix, and those which are actually announcing the prefixes to PCH's
    global network of looking glasses. The tool produces two lists of
    inconsistent origins: the list at the top of the page, which contains
    prefixes that are being announced by ASNs apparently unrelated to the
    putatively-authoritative ones; and the list at the bottom of the page,
    which contains prefixes with minor or apparently harmless
    inconsistencies, mainly subsets of large authoritative sets, and
    different ASNs operated by the same organization."

    It's updated daily at midnight UTC. We don't presently spam any lists
    with our various reports and analyses. I guess we could add a
    subscription feature, though.
