I think it's just your little corner of the woods that isn't adopting it. Over here the trend is very clearly to move away from IPv4, except for legacy reasons.
Save for the France/Germany (~75%) and then USA/Mexcico/Brazil (~50%) rest of the world is not really adopting it... Even in Europe Spain has only ~10% and Poland ~17% penetration but yeah... let's be dismissive with "your little corner"...
The important milestone is when it's safe to turn IPv4 off. And that's not going to happen as long as any country hasn't fully adopted it, and I don't think that's ever going to happen. For better or worse NAT handles outgoing connections and SNI routing handles incoming connections for most use cases. Self-hosting is the most broken but IMO that's better handled with tunneling anyway so you don't expose your home IP.
DS-lite (aka CGNAT), now we don't need to give the costumers a proper IP address anymore. It should be banned as it limits IPv6 adoption and it getting more and more use for "customers own good" and is annoying as hell to work around.
The graph indicates that only 50% of the samples have IPv6. Also consider:
> The graph shows the percentage of users that access Google over IPv6.
About 20% of the world population lives in regions where Google is outright blocked, so the above users with confirmed IPv6 reachability reflects no more than 40% of the world population.
I'd expect that IPv6 deployment will have a long tail end. Countries lower on resources but with relatively modern infrastructure are the ones who will delay the longest in upgrading to IPv6.
Adoption is not even 50%, and the line goes up fairly linear so ~95% will be around 2040 or so?
And if you click on the map view you will see "little corner of the woods" is ... the entire continent of Africa, huge countries like China and Indonesia.
Why did adoption slow down after a sudden rise? I guess some countries switched to ipv6 and since then, progress has been slow? It's hard to infer from the graph but my guess would be india? They have a very nice adoption rate.
Sadly here in Canada I don't think any ISP even supports IPv6 in any shape or form except for mobile. Videotron has been talking about it for a decade (and they have a completely outdated infrastructure now, only DOCSIS and a very bad implementation of it too), and Bell has fiber but does not provide any info on that either.
There's simply not enough demand. ISPs can solve their IP problems with NAT. Web services can solve theirs with SNI routing. The only people who really need IPv6 are self hosters.
Ah that's cool! It sucks that they are basically non existent in Quebec, at least for residential internet. But I think they are pushing for a bigger foothold here
