What total bozo blocks single IP addresses anyhow?  The chances it's a snowshoe
spammer are high enough that if you're going to go that route, you just block
the whole /24 (or more).

And if you can figure out how to block an IPv4 /24, the additional clue to figure out
how to block an IPv6 /56 or /48  isn't much.  And if you can't figure out how to
block a /24, the secret is to keep banging the rocks together...
