How can somebody else have the same IP as me?
Okay, so I was getting into an argument on a website with some people, then this other person was like "oh, they're just arguing with themselves", and at first I was like "what?", but they also posted a screen-shot, and what do you know? At least one of the other people has the same IP as me. How is this possible? Also note that I was on an iPhone using cellular data and 3G.
Added (1). Oh, and I should have pointed out that I have been using a fake IP proxy for the past week (securoty reasons).Is it possible that somebody could happen to coincidentally have the same IP as my fake one?
