Trouble is the storage required to do so. It is horrendous. As the article says
RFC6302 might help. Dual stack and static port assignments will do the trick in
the short term. I suspect the gov already has a backdoor.

? unless the ISP keeps a log of every IP address and where it came from - not a trivial task
Authored by: JamesK on Tuesday, June 05 2012 @ 11:39 AM EDT
If you use the MAC based address, then they have something that can be tied to
you. Some people considered that a privacy risk, so random number based
addresses were developed. This means that unless you know where it came from
that tie is broken. If you get an IPv6 address from an ISP, when you use a
random number address, the only consistent part of the address is the ISP's
subnet. Unless the ISP matches up the IP address with something like the cable
modem MAC or ADSL port, then there's no identifying info to provide to the
police.

BTW, those are 64 bit random numbers, which is an incredibly huge number of
possible addresses. As I mentioned, those addresses change frequently, compared
to my IPv4 DHCP address, which changes so seldom it's virtually static.
