Really need help regarding my IP.

OK, sorry in advanced if this has been asked before, I just didn’t find any topic related (or I could be blind, don’t know). I really need a hand and I’ve been to different message boards where nobody has ever replied, so I thought I could give it a try here.

I would like to know if there’s a way for people to see my IP address using either AIM, DEADAIM or any AIM related program. I know you can see it when you transfer a file or when you make a direct connection with someone else, but is it possible to view someone’s IP during a group chat or in any other way that isn’t either direct connection or file transfer?

Also, if this is possible, how do I prevent someone from seeing my IP in a chat on AIM when I’m using two different screen names? (I’m currently using AIM+ for the different IDs).

I’ll explain the second part better. I’m in a group where you should remain anonymous. I logged into the group chatroom with two different screen names and someone claims to know I was the one using both the screen names because they “saw my IP on the AIM IP log”. Whether this is possible or not, (I am sure this person was bluffing as there are many other ways this person could have known it was me, hints that are very obvious and easier than seeing my IP, that’s why I don’t believe them, but nevermind that… anyway…) but even when I know they were bluffing, I’m still curious to know if it is possible, and if it is, I would like to know if there is a way to prevent someone from seeing my IP in a chatroom when I login using two different (or more) IDs.

Thanks, I hope that made sense.
