alt Hacker NewsI was directly replying to someone saying they could subpoena the temporal owner of an IPv6 address, as though that were somehow different than IPv4.
The tracking is a moot point. You can be tracked using the same technologies whether you connect though v4 or v6, and neither stack has the advantage there.
IPv6 eliminates the possibility of proxies / VPNs. Being tracked simply by IP becomes non-optional.
