Why is it bad for someone to have your ip address? What can they do with this information?
In: 76
First there are two types of IP addresses. Private and public. Public ones are the ones that let the internet work. Everyone has 1 public address. If someone got that, they could scan your ip and possibly your whole network (based on if you are protected or not).
Your private address usually doesn’t matter much any more. Back in the day web forums often allowed admins to ban by private IP address. This could ban multiple people for 1 single IP address.
Story time: back in the early 2000s I was on a forum that allowed banning by IP address. This forum had everyone’s IPs shown. I made it a point to pointing it out. First I changed my IP address to match one of the mods. I kept at it until they banned that IP. So then I moved on to the next mod’s IP. Once all the mods were banned I changed it to match the admin trying to banned me. He then banned himself, and I simple again changed my IP. After a week or so the admin emailed me and I explained exactly what happened and how to unban himself. After he did, he changed the IPs to be hidden.
