1. Believing that changing IP adresses somehow help to protect your
privacy is naive.
2. Believing that NAT somehow help to enhance privacy is naive in the
same way as believing that NAT provides some kind of security!
All modern operating systems also support IPv6 privacy extension that
aautomatically randomly assign new IPv6 host parts to the network
prefix. I'm quite sure, that these privacy extensions won't help to
provide any additional privacy to the user but they seem to give a good
feeling to a lot of people.
So. I want a fixed IPv6 prefix from my ISP (if I need privacy I will
have to use Tor and other tools). And I like to have fixed addresses in
my network (fortunately, with IPv6 I can have several addresses per
interface really easy)
So I still hope to get IPv6 in Tahoe soon so we can finally get rid of
that stupid NAT and IP-Forwarding on our routers...
