The default IP banning stops an IP from accessing anything on your site via IP address. The problem I faced, and the reason I made the IP_NoView! version of this code was that I have several hundred AOL users on my site and ONE PITA psycho! To block all AOL IPs that this member used was impossible (when I gave up I had over 2-dozen blocked!). So, I created the second part using php functions to resolve the IP host so I could block at that level.
Now, because these hacks work off a hook location and they use a conditional so that only guests are affected, members are able to log in and use the forum as normal. I have other tools on the site that help me identify multiple accounts or multiple account registrations...
I created this because I needed it for my site and it has worked really well for me! That is why I decided to share it here and these two follow-ons pretty much use the same code.
