Sure does, but this indicates that you understand TCP and/or how AIM makes connections hence you're not going to make a DC with an unknown person.Aim gives you the ability to use a proxy during a direct connect
Also correct. However, exploits are outside of the scope of the question. Again, knowing an IP address is hardly a tragedy either by exploit or stupidity....and there have been programs in the past that used exploits to find any user's ip.
