My favorite thing to use IPv6 for is to use the privacy extension to get around IP blocks on YouTube when using alternative front ends. Blocked by Google on my laptop? No problem, let me just get another one of my 4,722,366,482,869,645,213,696 IP addresses.

I have a separate subnet which is IPv6 only and rotates through IP addresses every hour or so just for Indivious, Freetube and PipePipe.

Could you link the privacy extension in question I haven't heard of it

it's not a browser extension, its a SLAAC thing https://www.internetsociety.org/resources/deploy360/2014/privacy-extensions-for-ipv6-slaac.

TL;DR is that SLAAC used to use part of your device MAC to form it's IP, which would be trackable/fingerprintable. Now devices just pick the last 48-bits at complete random on the assumption that no other device is going to have that specific address out of the 4 quintilion available addresses.

edit the RFC https://datatracker.ietf.org/doc/html/rfc4941
