If there aren't too many actual *IP*s then you might look into
ipt_recent.  It does more than you actually need but I've put 1.5M IP
addresses in an ipt_recent hash before.  Many more than that and
ipt_recent runs into problems because it can't allocate enough memory w/
the default kernel memory setup.
