Some interesting stats from <https://www.tomshardware.com/networking/ipv6-usage-reaches-historic-50-percent-across-google-services-matching-ipv4-increased-usage-eases-pressure-on-the-ipv4-address-market-as-new-protocol-designed-in-1998-finally-hits-its-stride>:

• 50% of users of Google’s services connect over IPv6
• 43% of the world uses IPv6, with some parts approaching 50%
• Cloudflare reports 40% of its traffic is done via IPv6

Choice quote:

Some people still think that the additional 20 bytes or so of an
IPv6 packet header translates to significant bandwidth losses,
higher CPU usage, and hair loss. The reality is that even 11 years
ago, Facebook's tests saw that IPv6 connectivity was around 10-15%
faster overall, while networking giant Akamai noticed a 5% speedup
in mobile page loading. The speedups are almost assuredly due to
the fact that with IPv6, there's very little need to do math with
NAT, proxies, and other shenanigans, as in most instances,
everything can directly connect to everything else.

The apnic has more detailed statistics, also possible to filter by
country or ASN.

I disable IPv6 on everything as habit.

Apparently that cuts me off from accessing newly provisioned younger
parts of the internet, most that are either scam territories or AI farms.

No loss.

Almost all abuse that I see (spam, phishing, cracking attacks, excessive
port scans, SQL injection tries) is using IPv4.

Same here. Having worked with IPV4 almost since its inception I have
no inclination at this late date to learn IPV6. Just don't care to
deal with it.

No loss.

I'd agree. I've been able to get to anything I need to via IPV4.

I ended up having to turn IP v6 support at the router as it was messing
up my DNS.

I run some Pi Holes. I had set the IP addresses of MY DNS to
192.168.0.29 and 192.168.0.30 and also set their corresponding IP v6
addresses in the router.

All my PC's wired to the home network were all using these DNS no problem.

However, all my mobile phones decided to use Google DNS even though I
could see the Pi Hole DNS settings in the network settings on said phones

Even when I installed a WIREGUARD VPN server and installed the clients
on my mobile phones. The problem persisted over VPN.

I ended up turning off IP v6 support in the router and the problem has
gone away.

Strike 1. Nobody is going to run a serious (= money-making) service that
isn't IPv4 accessible.

Strike 2. The fact that thse words are repeated over and over suggests something is very, very wrong with the way IPv6 has been handled.

Millions of people use it every day without issues. Some device or even
just configurations are faulty. In that case please investigate the
issue and report it to the manufacturer.

IPv6 is not the issue here. Certain operating systems and applications
(e.g. browsers) use DNS over HTTPS for name resolution instead of the
OS resolver functions, so the servers you distribute via DHCPv4, DHCPv6
or the router advertisment will not be used.

I think large parts of Asia are connected purely via IPv6. This is not
a matter of choice, but of necessity, since the Western regions had
gobbled up most of the IPv4 addresses, and so there were none left for
the billions of new users.

So How do I force or redirect *every* device that conencts to my network
to use MY own 2 DNS rather than wandering off and using an external DNS
like Google's own DNS?

Block the IPs of external DNS servers.

If a device decides to DIY its own DNS (or DoH or DoT), there's nothing you
can do to stop it - no setting in DHCPv4, DHCPv6, RAs is going to prevent
it. Only if it can't reach the external servers might it fall back to what it's been told in local config.

Why would you want to? Advertise your routes so that external DNS servers
like Google know about them.
