More than 1/3 of all access to Google is now over IPv6

That's scaremongering and simply false. Cgnat servers are not necessarily congested. I've been to several isps with cgnat and none of them suffered from congestion. On a more personal note, if ipv6 were so great, their fans wouldn't have to make up things to badmouth ipv4.

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.

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.

These ISPs are using DS-Lite, Dual-Stack Lite. https://www.juniper.net/documentation/en_US/junos/topics/top... (this isn't a purely Juniper thing, but they have nice diagrams on their documentation) It's a kind of carrier grade NAT with 4over6 baked in. Depending on the version of this they are relying on your modem to perform encap/decap of 4to6, hence when you switch to modem mode or your own router you fall back t…

Yes, tonnes of benefits. If you've ever been through a merger, you'll know the pain of dealing with getting the everything working when merging networks. That issue doesn't exist with IPv6 to anywhere near the degree because you don't have overlapping RFC1918 space to deal with. IPAM with IPv4 is a massive pain in the backside once you get up to a certain scale, even if you're allocating from 10/8. If you have multip…

Well - you may have overlapping RFC 4193, but if your network engineers have done their job well, you are randomly choosing from a big honking FD/8 address space, and the odds of a collision are statistically very unlikely.
