All we need is ONE major website to declare 24 Hour brown-out for IPv4 and put a message something like "Contact your ISP to upgrade your connection". Alas, publicly traded companies....

Think you will need more than that!! Rollout has stagnated for over 20 years.

At this point I'm personally convinced that ipv6 is a failed technology. It used to be interesting to see the news about new ipv6 deployments, adoption ratings etc. Now I basically don't care.

I recently moved, and was mildly annoyed to find that my ISP didn’t assign me an IPv6 address. Then I remembered that, in order to get one at my previous location (same ISP), I had to call and specifically request it. That was six years ago . If they haven’t defaulted to giving out IPv6 addresses by now, it’s never gonna happen. I honestly can’t figure out why they don’t, as it has to be cheaper to just do it than ma…

I will be calling to complain if I am not assigned an ipv4 address by default. Very first thing I do whenever I move or get a new router is disable all ipv6. All of my client devices have ipv6 disabled. ipv6 takes a very simple addressing schema and unnecessarily turns it into an entire beeping protocol for no reason.

I don't care if I have to write angry letters to senators to pass laws forbidding the sunsetting of ipv4, this is 100% an issue I will go down fighting tooth and nail until I die or ipv6 dies, whichever first.

Never is long time. I bet you that they will be providing ipv6 as default in 20 years from now if they are still in business.

A failed state using a failed technology, how befitting!

Setting up IPv6 on my home network was fun and exciting now it's just boring. The only time I've noticed it was was once when IPv4 broke (dhcp server issue) and another time when IPv6 itself broke (radvd issue). All that said I do sort of wonder when or if we'll ever move off dual stack. I think there's a strong argument that running two protocols at once is riskier then the combined risks of the two.

I can't imagine too many businesses will be switching to it internally unless forced to. ISP's and mobile carriers are one thing.

What happens to all old software that is more or less "hard-coded" to use IPv4 addresses? Will there be an OS layer that can run an app in IPv4 compatibility mode of some sort?

464XLAT should be the solution for this [0][1]. Requires network and OS support.

Does anyone know why German universities are so slow to deploy IPv6? Almost none has their website reachable over IPv6 or IPv6 on their internal network.

Most German universtities have applied at an early stage for a class B network block therefore they have little pressure.

When I asked the IT staff at my university years ago, they said that there are still some very old routers without IPv6 support in use. And since everything seems to work with IPv4 for the university administration, there is no money for new ones.

I like it, but you could do it without a brownout. Similar to the ipv6 test websites, have the major site check ipv6 and put up a banner with your message.

Citation "IPv6 was designed to restore the end-to-end model of communications with all nodes on networks using globally unique addresses. But considering this, IPv6 may imply privacy concerns due to greater visibility on the Internet."

IPv6 is actually better for privacy.

First, the IPv4 address space is tiny. Say, a PING packet is 84 bytes, so pinging the entire IPv4 address space will take you all of 336GB of traffic each way (not even accounting for the reserved parts). That can be done in the space of an hour in a decent connection. So things can and are being trivially found by brute force. If a vulnerability is found in something interesting you can bet that by tomorrow lots of nefarious people figured out who can be broken into.

Second, IPv6 has the privacy extensions, which means that even if somebody knows your address today, this has a very limited lifetime to it. Privacy extensions regularly randomize your IP address.

Under IPv6 even normal people can get more address space than can be reasonably scanned. This makes it harder to identify machines permanently, makes it harder to figure out how many machines there are and makes brute force scanning extremely impractical.
