>But in most OSes the right part is randomly generated and changes on some cadence (e.g. daily). >So in many cases, the ability for a server to individually fingerprint your device solely based on the IP address is roughly equivalent between IPv4 and IPv6. That still makes ipv6 strictly worse, if you consider that a device is always uniquely identifiable at any given time, whereas with ipv4 NAT they can't be individually identified.
