(shoulda read this whole thread before I posted the earlier suggestion) If the program you're using to ban subnets is really working, this shouldn't be a problem. Seriously, without a very difficult amount of work could a person just grab IP address's to use at random. This is why I think that if what you're saying is true about this person grabbing random IP's, the software you're using to check and verify a person's IP address is flawed. Banning class b's(x.x.*.*) and class a's(x.*.*.*) won't really stop the problem, and you're probably just shutting people out of your site that aren't doing anything wrong. Again, unless this person is pretty smart, or they're using some sort of script-kiddie software I've never seen, there is no way that they can just magically change their IP address.(unless they have an unlimited number of shell acounts to post to your site with a program like lynx, in which case you're hosed) What kind of software are you using to do the IP resolution? .djc.
