Yep, and even with all those countries with their billions of mobile devices IPv6 use still hasnt even reached 50%.

Pretty much all ISPs hand out both IPv6 and IPv4 addresses to their clients, this is nothing new. When they start only issueing IPv6 IPs is when it would start truly taking off, but it will never get to that point and it will never happen.





It feels like you are constantly moving goal posts here. Your original statement was it will die a slow and quiet death. Are you now saying that this mobile use case will start to switch back to IPv4? It may not kill IPv4, like was initially planned, but it's not going away.

Apologies maybe slow death was the wrong phrase. I did mean that, but only in the non-mobile space. Obviously mobile device networks have made good use of IPv6 and will continue to.

However In another thread it was argued that when IPv4 addresses become very expensive, that could trigger a big shift to IPv6. I agree with this statement and so IMO it is possible that IPv6 may well become ubiquitous in the future.


When usage is increasing rapidly and is literally ~ 50% of the entire planet right now, how is ANY kind of 'death' a useful descriptor?

IPv4 is the one that descriptor belongs on, eh?


No I dont agree at all.

Usage is in no way 'rapidly increasing', in fact the google graph everyone is touting around shows that it has taken over 10 years to not even get to 50%. It also shows it is slowing down, the curve is starting to become less steep.

When Maximum possible IPv6 usage is not even at 50% after over a decade and the usage curve is slowing, how can you possibly say that IPv4 is dying and IPv6 usage is rapidly increasing?


Oh, now it’s a problem because it’s been about a decade?

So what, another decade and we should be mostly done?

What do you think is a reasonable amount of time to redo the entire world’s networking infrastructure across 200+ countries and 8 something billion people, exactly?

This is an absurd argument, you know that right?


> Oh, now it’s a problem because it’s been about a decade?

No, but taking over a decade to not even be half adopted does not count as rapid in my opinion.

> So what, another decade and we should be mostly done?

No, as I have said many many times, the graph is slowing.

> What do you think is a reasonable amount of time to redo the entire world’s networking infrastructure

We dont need to, thats the point. All networking equipment in the world already supports IPv6, so why isnt it at 100% usage and IPv4 is turned off already?

>This is an absurd argument, you know that right?

Who is the fool, the person saying what they think or the person continuing to participate in an argument they consider absurd?

You dont need to make everybody in the world agree with what you are saying, it is ok to have differing opinions. You know that right?

I am done now. I accept that you disagree with me and thats fine. Can you afford the same decency or will you continue to tell me I'm wrong?


Hahahahaha

According to APNIC labs, IPv6 adoption in India is ~79% and in China it is ~53%.

Those are the only two countries that could plausibly have billions of mobile devices and they appear to have reached 50%.

Wow, billions of devices per country and they have still only reached 50%.

Damn, the jealousy (?) is palpable. You know you will have literally zero impact on adoption no matter how snarky you are, right?

Jealousy? I think you may need to expand your vocabulary a bit!

I have an opinion on something, I assume thats ok? You seem to be here trying to prove me wrong, and also commenting on my tone of reply.

Im not trying to tell you that you are wrong, only stating what I think. If you dont like my opinion, feel free to ignore it. You are not forced to comment.


Looks like it’s right at 50% and rapidly increasing.

[https://www.google.com/intl/en/ipv6/statistics.html]

What exactly are you going on about? 5-10 years for the old devices to be EOL’d, and we’ll likely be at 95%.


Devices maybe, software won't :-\ (We're going to see ever-diminishing pockets of IPv4 around for a loooong time, much like we still see pockets of Cobol.)

pick a lane?

The trend on that graph is slowing, and when we reach criticl mass on the number of mobile devices the graph will be flat.

There is no chance we will be at 95% usage in 5 years or so.

If you like, we can make a wager?
