extract hostname from url, dig on hostname, whois on addr, and nine times
out of ten the host is in a CN netblock. that's from the spam that gets
into my mailbox.

let me state AGAIN that what I really want is a plugin that allows for
cidr match-lists so that I can also include the handful of non-enforcing
hosters in Russia, New York, Florida, etc. One responder also suggested
ASN matchlists but I'm not that mad.
