IPv6 which the advanced countries are now using on their cell networks gives every phone a public IP.

IPv6 suuuuuuuuuuucks 🖕🖕🖕
What problem do you have with it? What ISP or VPN?
Administering it 🤢
Clearnet IPv6 is a whole lot simpler than IP4 IMO. Right off the bat, there is no NAT nonsense. The only annoyance I've had is that too many devices (like network enabled printers) only support /64 subnets.
The IPv6 mesh is even simpler. The only thing you might configure are some remote peers (LAN peers are automatic).
Big Tech will never fully support IPv6 - IPv4 forces consumers to use centralized services.
I recommend IPv6 mesh VPNs like Cjdns, Yggdrasil, Pinecone. Every device gets a permanent cryptographically authenticated IPv6 that is also mobile. A SIP client can use the raw IP in the contact list - no need for telco, DNS, or TLS.
Where IPv6 is supported, the mobile IPv6 protocol (easily self hosted) lets an IPv6 on your net be anywhere that support clearnet (normie) IPv6.
Neat, i should look into it more. Probably won't get adopted until painfully late , like https.
