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.

    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

    This is exactly why ipv6 was never widely adopted. There's too much power in a limited IP pool.

    Define "widely".

    According to Google 46.09% of their traffic is IPv6 and most servers support it. It's mostly large ISPs dragging their feet.
