> Where did you get your info? I did not read anywhere that he was using someone else’s I.P.
Read the article. His computer. He lived in a home with other people and he was using the IP address of one of the other residents. In my opinion, he was using the other address and not his own, so things wouldn’t get traced back to him.
It does not say that he was using the IP address of one of the other residents anywhere.
As Billthedrill pointed out the most likely scenario is a home router. if that was the case (99% likely) then he had no choice but to use the same address as all of the other residents. That's because they all use the address of the router. That is the only address that can be traced. All the residents are assigned an internal address by the router, but that doesn't matter at all and it would not matter if he used an internal address of another resident, it would not change anything externally.
The 1% possibility is that there was no home router, and the provider assigned addresses to all the home users. But in that case he could have used an address from someone across town. It is very unlikely that they would mention the home users without it being the home router scenario.
