I bought an iPhone from AT&T, have nothing but problems with it. Checking my IP address, I have one from AT&T, another one from Hetzner. The same thing happened with my previous iPhone from AT&T. When I access a webpage, the page comes from multiple servers, each sending me a piece of the site. I seem to believe that some cellphones are made with 2 OS', in my case an iOS, the other with a BSD version. They call them 2 in 1. It is extremely difficult to detect this, many, very many developers are involved and they are experts in hiding the fact. I have contacted Apple many times over this but they deny it, they say it's not possible. But it is true and these people have been making me penny less over the years, they won't allow me to work anymore and often when I call a company, my calls are intercepted and one of these people belonging to this group. This group is huge!
I think that would explain the issue that you're talking about. Sometimes the Internet source gets mixed up and you see Hetzner instead of the ISP which a user has the data plan with. I have been told not to check my IP address by some Apple Senior Advisors. They say you could get viruses and these sites which display your IP are not accurate and can't be trusted. I was just told that 2 days ago by Apple when I complained about my second connection to Hetzner.
