For some reason when I plug in an IP to check it in the database, I'm not currently getting the little list of close IPs which has usually been at the end of the entry.  Is it just something screwy with my computer, or does that only show under certain circumstances?

I'm asking because I'm banning some troublesome ranges from my forum.  For instance, since I have spammers registered from 123.125.156.131, 123.125.156.134, 123.125.156.145, and 123.125.156.196, I figure maybe I can just ban the whole darned range of 123.125.156.*.  Being able to check nearby numbers in the database is really helpful for this.
