I recently changed the name of my private wifi at home. Since it was related to Harry Potter, I posted a picture of the new name to a Facebook Harry Potter fan group. After a few hours, I got a couple of comments. One thing that I had not noticed when I took the picture was that I had inadvertently also gotten a shot of my IP address. A few people told me to take it down because other people could use my IP address for inappropriate actions. I had to research this a bit. I did not know that this could happen. Thankful that someone pointed it out to me, but sad that I have to be so careful with even a seemingly harmless picture.
