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&amp;#x27;s very fuzzy.&lt;p&gt;&lt;i&gt;&amp;gt; With IPv4 my ISP has to shuffle IPs with every reconnect. With IPv6 you could get one IP for lifetime?&lt;/i&gt;&lt;p&gt;Your ISP can hand out a new prefix whenever you connect, or even while you are connected. Most of them do this by default.&lt;p&gt;&lt;i&gt;&amp;gt;While ISP that hand out a static IPv4 can exist, it&amp;#x27;s much more unlikely, whereas with IPv6 it will become the norm.&lt;/i&gt;&lt;p&gt;it doesn&amp;#x27;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&amp;#x27;t even offer the option of getting a static prefix.</text></comment>

And address allocation policy is independent of which protocol you&amp;#x27;re using anyway.</text></comment>
