NAT is great in that it obscures individual machines without too much lose of functionality.
- andrewaylett 8y agohttps://tools.ietf.org/html/rfc4941 https://tools.ietf.org/html/rfc4941 defines IPv6 privacy extensions, which mitigate that issue. One of the few benefits of an extended roll-out of IPv6 is that there's been time for people to identify issues like this and get fixes rolled out widely before systems started relying on the old behaviour.
- mehrdadn 8y agoWhat percentage of IPv6-supporting routers have implemented and activated those privacy extensions?
- detaro 8y agoIt's a feature of the client device, not the router, and is implemented in all major operating systems. They are not perfect though, since at least the original design was purely timer-based, which left some tracking potential.
- mehrdadn 8y agoThanks for the correction, and yeah, there you go.
- gigatexal 8y agocouldn't you get around this by wrapping all tcp/udp connections in an encrypted manner say a tunnel and using dns+tls to encrypt dns queries? Sure it's not as easy as just using NAT but not having to translate via NAT to get to the internet sounds good to me. Access points wouldn't need to route anymore would they?
