What I missing? IPv6 just look like privacy nightmare.

There are placebo solution for “privacy” with daily generating new IP, but that is only placebo.

You need to be identified only once per day and after that? If you are identified by google and for some reason you use google DNS they know what URLs you resolved.

Is possible to have IP per connection? It's against that IP is for interface, but IPv6 can have expired “placebo” IPv6 so maybe it can be solved with milions of IP adresess daily?

You can change these sysctls values:

temp_valid_lft - INTEGER

valid lifetime (in seconds) for temporary addresses. If less than the minimum required lifetime (typically 5-7 seconds), temporary addresses will not be created.

Default: 172800 (2 days)

temp_prefered_lft - INTEGER

Preferred lifetime (in seconds) for temporary addresses. If temp_prefered_lft is less than the minimum required lifetime (typically 5-7 seconds), the preferred lifetime is the minimum required. If temp_prefered_lft is greater than temp_valid_lft, the preferred lifetime is temp_valid_lft.

Default: 86400 (1 day)

Thanks. That is great, but i still see limitations with connection opened is same time.
