Amusingly that's how mobile/smartphones are supposedly run: the devices get IPv6-only, and if they need to hit an IPv4-only address they are CGNATed.

Ah, so that explains it. I just switched from Sprint (which always gave me an IPv4 address) to T-Mobile (which gives me an IPv6 address).

My Verizon iPhone has both a public IPv4 address and a public IPv6 address.

They certainly could be using CGNAT, but that seems like a weird way to do it.

How are you able to tell with IPv4? You cannot run ifconfig on an iPhone, so how are you determining that?

There are apps like "Network Analyzer" that give you this info. (My MVNO puts me behind CGNAT, no IPv6)

Seriously? On Android it's just settings->about phone

Really? My Verizon Android gets RFC6598 space.

Holy cow, I don't know how I was never aware of RFC6598. When I saw the address starting with 100, I simply assumed it was an actual routable IP.
