<p>Yes, you can use “war driving” (personally, I would use a proxy server if I was trying to conceal my internet activity as it would be very obnoxious to war drive for the number of posts that asian75 has posted) but if that were the case, why did he not tell us what cut offs were?</p>
<p>Your question was slightly ambiguous, I couldn’t tell if you were asking how would you be caught if you were war driving or how would you get caught if CC released your IP address. If you are war driving, you probably will not get caught so you would be free to tell the cut offs, which he did not do. If you are not war driving or using a proxy, and someone finds you doing illegal activities online, they can find out who you are from your ISP by asking them who was using that particular IP address when the activities happened. Yes, ISPs do keep those kind of records.</p>
<p>Knowing some ones IP address alone will not enable you to find out who they are. People are assigned a different IP address by their ISP every time they go online. The only way to figure out who some one is from their IP address is to go to their ISP and ask them to tell you who was using that particular IP address at that time. Your ISP will only release that information if there is a legal reason to do so.</p>
