Here’s the routing table that the HE.net Network Tools shows for my cellular connection shortly after I’ve turned off WiFi on my iPhone 14 Pro.
None of the entries in the cellular routing table is IPv6 with my current SIM card. So I am doubting more and more the claim that iPhone is somehow IPv6 only.
Seems more like some people have carriers that choose to provide them IPv6 only, and because of that they think that it has to do with the iPhone itself.
