> Is it reasonable to hate and avoid IPv6 for fears of further privacy erosion (easier tracking than with IPv4)?
no. If an ISP assigns you a dynamic prefix and the various machines in your network use any one of the various privacy features like temporary addresses then the only additional information you leak is some information about how many devices are in your LAN, but as the devices make up additional addresses, it's very fuzzy.
> With IPv4 my ISP has to shuffle IPs with every reconnect. With IPv6 you could get one IP for lifetime?
Your ISP can hand out a new prefix whenever you connect, or even while you are connected. Most of them do this by default.
>While ISP that hand out a static IPv4 can exist, it's much more unlikely, whereas with IPv6 it will become the norm.
it doesn't look like it - at least here in Switzerland, all providers that do provide v6 addresses hand out dynamic prefixes by default and most don't even offer the option of getting a static prefix.
- vetinari 8y agoTechnically, per IPv6 Address Allocation and Assignment Policy[1], there's no such things as a static IPv6 address, only address leased for a long enough period to be effectively static.

- _trampeltier 8y agoIn switzerland we have still no IPv6 on mobile phones at all in 2018 :-( With my provider green.ch it is not possible to get a static IPv6.
- nickik 8y agoYou can get static IPv6 from Fiber7.
- pilif 8y agoI know. And they even delegate the ip6.arpa domain so you can do reverse lookups with your own DNS server. source: I'm fiber7 customer since 2014 and they offered me to do the delegation when I asked them for the static prefix.
- nickik 8y agoNice. I had the FTTH.300 and only got Fiber7 yesterday. I don't have my own DNS as friend hosts my stuff. The static prefix is nice and they will also basically give you static IPv4 even without paying.

- pilif 8y agooppressive regimes will assign people static IPv4 addresses tied with their legal identities.
- bcaa7f3a8bbc 8y agoIf IPv4 pools and carrier-grade IPv4 NATs spreads all over the network, a user's identity is revealed to the oppressive regimes in primarily two ways: a) IP pool logging, requires a known IP address and time. b) NAT logging, requires a known IP address, outgoing port number, and time. It means the cost of tracking users is moderate to ISPs and authorities, also, for a random observer without access to internal records, a IPv4 user is effectively pseudonymous to the city-level until enough information is revealed. But if the oppressive regimes really assign assign people static IPv6 prefixes tied with their legal identities intentionally, without any type of privacy extension, it would mean after I use my network connection for a while... __everyone on the Internet, not just ISPs, can track my activity, possibility tied with my legal identity.__ I'm well aware of the existence of mass surveillance on IPv4, and I'm not advocating IPv4 for a false sense of security, I'm all for IPv6. But this is a true issue for consideration. Using a VPN, or Tor for day-to-day web browsing is the only practical solution to this problem I can think of... On the other hand, IPv6 will bring end-to-end communications back to the Internet and revive P2P. To that day, perhaps a P2P-based, full mesh, optionally anonymous network will become practical. To this extent, IPv6 does more good than harm.
