IPv6 traffic crosses the 50% mark

It has barely hit 50% and it's already plateauing. This adoption rate is ridiculous despite basically all network interfaces supporting it. I thought I would see IPv6 take over in my lifetime as the default for platforms to build on but I can see I was wrong. Enterprise and commercial companies are literally going to hold back internet progress around 60 to 75 years because it's in their best interest to ensure users can't host services without them. Maybe even 75 years might be too optimistic? They are literally going to do everything in their power to avoid the transition, either being dragged out kicking and screaming or throwing their hands up and saying they can't support IPv6 because it costs too much.

Try going IPv6-only by disabling IPv4 on your computer as a test and notice that almost nothing works except Google. End users shouldn't need to set up NAT64/6to4 tunneling. It should be ISPs doing that to prepare for the transition.

Also, notice how Android and iOS don't support turning off IPv4.

Every company I have ever worked for in the US didn't use IPv6 and actually blocked it at the FW

It's been amazingly linear since 2014.

amazon.com needs to get with the program. Still IPv4 only.

Nice. But note that the average is still significantly below 50%. It's also a bit concerning that the growth rate seems to be levelling off. It currently looks like a sigmoid curve with a maximum far below 100%.

The question is, "what will the graph look like in the next 10 years?"

I get the whole s-curve trend but if I squint at 2017, there is an inflection to slow the s-curve down.

Annoyingly, when setting up service with a fiber company in the last couple months, I explicitly asked about IPv6 connectivity and they said, "yes." Turns out "yes, but not in my region."

while it looks like its slowing down, I am pretty sure it will speed up once IPv4 get even more expensive, sites start to be hosted on IPv6 only and become inaccessible to some users that dont have IPv4. Thats surely going to put pressure on ISPs
