Lately I've seen many strange events in the logs of my wifi router / cable modem. Many are linked to the IP address 184.108.40.206 from the ISP, Orange Polanska. Events like "DoS attack: Ping Of Death", "DoS attack: Teardrop or derivative" etc.
However today the situation rose to a new level: The IP address was no longer limited to appearing in the logs of outside attackers. It now appeared to be one of the devices on the Wi-Fi network. See linked photo: http://imgur.com/YFgLBCJ
The Mac address of the device suggests it is an Apple device. At one point the name of the device was the same as the name of a roommate's iPhone. I asked the roommate if he was using a VPN on his phone, and he said no.
Is it possible that person from Poland has in fact enter the network?
If the iPhone was hacked, why would it appear on the Wi-Fi network as a Polish IP address?
FYI, I asked Orange Polanska twice to shut this attacker down and they have not done it.
