I've identified that my wife's iPhone 6s swaps between two IP addresses on our home network (Router: Netgear C3000, ISP: Comcast). All IP addresses connected to my router show that they start with "192...", but this alternative IP it connects with is "130..." and it matches the source IP causing the DoS attacks in my router log. I've confirmed on her iPhone that the Wifi MAC Address always stays the same. She has an Apple watch connected to her iPhone as well, but this problem had occurred prior to that being around. This issue appears to be the source of our internet dropping out almost daily lately. Any advice on how to resolve this issue?
