Why are is there such a difference between countries?

Could be ISP adoption. Some ISPs have been more progressive in ipv6 than others.

My ISP in the Netherlands (Ziggo) provides me with native IPv6 if I use their supplied router, but forces me onto IPv4 when I use theirs in bridge mode in conjunction with my own router.

Still not sure why they do that.

The graph is interesting when you zoom in, much more IPv6 use over the holiday period and also recently during the period of lockdown measures. I would guess the majority of IPv6 traffic comes from devices on 4G networks. More devices are on 4G when visiting family and friends over the Christmas period and when working remotely.

It's not just 4G. It's consumer networking in general, which isn't held back by legacy enterprise networking equipment. When your residential ISP turns on IPv6 for their network, they also tend to turn on IPv6 for the modem+router combo devices they lease to run your LAN. Or if you're the kind of power user that buys your own router, it's almost certainly new enough to support IPv6.

Earlier quoted context omitted.

Nearly all modern operating systems use the IPv6 privacy extension, which creates random addresses periodically. Thus the tracking is randomized to the /64 (which is an end customer). This is more or less the same as with IPv4 (without CGNAT)

Irrelevant. It's within your subnet, and it's nowhere near 32b. https://www.transtutors.com/questions/how-many-bits-are-need...

yeah, like when you have a /32 IPv4 dedicated to your private subnet; it's the same.

In Australia I get a /56 block

I'd assume it's because they expect that if you are using your own equipment it could be older and by just forcing v4 it reduces support costs. 100% pure speculation.

It's a perquisite for tagging individuals. IPv4 not having enough addresses is a good thing. With IPv6 identification (and therefore control) can be down to the person globally, but IPv4 forces NAT's. The inability to label all the things is a feature. NAT's are borders; they prevent fine grained censorship without larger consequences. $ zcat /proc/config.gz | grep -i ipv6 # CONFIG_IPV6 is not set

Not just tagging many ISPs especially FTTH/P don’t randomize IPv6 addresses so all the IP addresses in your town, neighborhood and even building share the same prefixes and they are hierarchical so by just knowing your IP address one could figure out where you live.

Network-wise this is a feature. Having the address space reflect network layout allows for vastly simpler, thus more efficient, routing tables.

Why use IPv6 if you are going to hand out IPv4 addresses?

People know why. Even if a few really get 32's, it's PR. The endgame is the same.

This is a critical path item for removing the ability to have 2 party value transfers. The power at stake is incalculably valuable.

I have the same situation with Vodafone Cable in Germany. I was told it is because of 6-to-4 bridging. A customer on IPv6 must be able to bridge to IPv4 to reach IPv4-only servers, but a customer on IPv4 will probably never encounter IPv6-only servers (except when using an IPv6 testing tool).

I'm not a networking expert, but AFAIK there's nothing stopping them from making their 6-to-4 bridging available to customers with a custom router. However, getting that stuff up and running correctly can be tricky, so it would involve a lot of support burden on the ISP's side. Hence why they don't offer that, they just drop those customers down to a configuration where the customer gets to use well-known protocols only (IPv4 and DHCPv4 over Ethernet).

Your subnet is no more uniquely identifying than a (non-CGNAT) IPv4 address; if 32 bits identifies which router you're using (whether that's your home, coffee shop or whatever) then a 64 bit identifier doesn't make that router any more identified.
