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.
Interesting. I was always under the impression it was the other way around. That linking a public IP directly to a device was potentially a privacy problem and that it was more private to access the Internet through a NAT.
Ok forget it I didn't read the whole thing
For clearnet IPv6, that could be an issue. But just as with IPv4 - use a VPN if you want to obscure your IP. The Linux IP6 stack will listen on a stable IP, but make outgoing connections on a random one that changes periodically. So at least that obscures which machine on the LAN is making to connection.
