I think the fundamental problem with ipv6 is that it's a bit more complex to learn than ipv4 and not universally deployed at the remote host/server level.

New cloud companies who want to be competitive have to purchase ipv4 blocks at significant cost reducing their ability to compete with the incumbent players.

So if you go 100% ipv6 at home, some percentage of the internet will be inaccessible to you unless you employ some workarounds.

We'll drop ipv4 quite fast once everything is up on ipv6 because nearly every modern network enabled device supports it.

The only reason I think we've not gotten over the hump is because our alternatives are still easy enough to work with and nobody requires it.

The goal today isn’t to make single stack IPv6 internet practical, it’s to make dual stack ubiquitous. Once that’s achieved, the cost differential, and the increasing technical burden of maintaining IPv4 hacks, will reach a tipping point where it’s relegated to legacy status, but this is at least a decade away, with likely another decade of inertial decay of public IPv4 after that.

IP being scarce is a business. It makes so IPS could charge outraging amounts of money for a stable exclusive IP. I do think many people don't want to let the golden cow die. Specially if there's a migration cost.

My ISP doesn't provide IPv6, and with other ISP using CGNAT instead don't think that IPv6 will be the main standard any time soon.
It's more of "if it works, don't fix it", just apply workarounds like tunnels

They both have use cases and are interoperable. I don’t see why folks think it’s so odd that they are both used and will likely continue to be used. It’s hardly even a topic worth talking about. Seems like one of those things people hear about being around for a long time as an updated standard and it’s some kind of gotcha that not everything uses it…What driver do these people imagine exists to not use IPv4, the addressing limit was solved before IPv6 even hit the street and has only matured and integrated with IPv6 since.

yeah, I don't see the benefits of moving to ipv6 outweighing the costs

I blocked all my IPv6 because android/Google would always force it's own DNS on me. And I couldn't find a reliable method without rooting the phone to turn this off.
Well i did find one, to disable IPv6 on the router. Is this a thing anyone else had or did i remember it wrong or not dig deep enough?
