Hi all.

Question: Recently I was in a java based chat room, thru internet explorer , fully up to date.
One of the chatters managed to resolve my isp and began to actually resolve my current IP. The client in question is unknown, but has no tools to do this as in some IRC clients. This is sort of worrisome. I've tried all over the net to find the utility he used. He was not a room moderator. The site that runs the chat client is not saying a word, so wondering if this is a vulnerability on their part as well.
Commenst and answers appreciated.
Cheers
Bob
