Is it critical to keep your IP address unknown to others? I have noticed that years ago message boards would post your IP address with your post. Now, most don't. How dangerous is it for someone to know your IP? Also, if someone REALLY wants your IP address and are computer savvy, can they get it? The reason that I ask is because I have a certain forum that I frequent (a message board related to football) where each member is supposed to have one handle and one handle only. Each person that visits the board is limited to 30 posts per day. I'm fairly certain that certain people have more than one handle based on writing style. But without seeing the IP address you can't know for sure. I have asked the board moderator to post IP addresses but he says that this would be a security risk. Thoughts?
