I had a problem with some idiot that kept plaguing my FORUM with harassing messages. I found out that he was using three (3) IP's: one.. a private one, with a certain HOST (I got the name). The other two showed a certain University as the HOST. When I confronted him with this info, he finally stoped harrassing us.
Now he's back, and the IP he's using shows as;
"IP exists but does not resolve to a host name".
Does anybody know what this means? Does it mean he's using an ilegal IP to continue harrassing us?
He might be using a proxy server to hide his IP. There isn't realy much you can do unless you password protect your site or forum. The one that they give you for free on bravenet isn't a good forum. You should try going with one at proboards.com then you can link to it. It is much more customizable and can have password protection, and have where only members can post, and you can block ip addresses.
