I have read a few threads where people are saying that they either share a wifi with someone else or they allow someone else to share theirs. I am wondering if there is any danger beyond the slow down that might happen if you both use it at the same time. Correct me is I am wrong but both users would show the same IP right? Has anyone that does this ever had a problem because two households have the same IP? I have noticed that there are things that I log into at work don't want to let me log on to them easily from home, I get some crazy message they don't recognize the machine or some non-sense. Does things like this happen more often if you actually share a service? I would think in this day and age people are mobile and log into stuff from all different places, but I do know IP addresses are still pretty important in some platforms. Just a crazy thought but what if your neighbor hated you, opened a free email and sent something to someone else that was awful- it would look like you and ultimately you would be responsible as the owner of that IP wouldn't you? While I am sure no one would give someone that hates them that sort of access I do wonder what sort of bad things could happen from sharing a network.
