Negative aspects of IPv6?

“IP Address as Tracking Devices

“Yes indeed, IPv6, by being able to directly address “every
grain of sand in the oceans”, recovers one of the lost attributes
of the early Internet: direct connectivity of every device to every
other device.

“But when every device has its own address, the dreams of those
who would track what people do and when are greatly enabled as
well. “You downloaded that movie to your toaster!” And with the
possibility of being able to take your address blocks with you when
changing ISPs, that problem only gets worse.

“This is not an IPv6 problem, the problem of Internet tracking
exists right now. Every packet can be traced, every connection
monitored. Anyone who thinks that IPv6 makes the problem worse may
be correct to a degree, but IPv4 does nothing to prevent the
problem in the first place. This must be addressed as a problem of
networking itself, and the laws and law enforcement terms under
which humanity operates.”
