Time for my regular experiment of seeing how much of my work still needs IPv4. So far I've had IPv4 disabled on my desktop for 4 hours and not noticed anything but duckduckgo and github broken. #NoNATNovember #ipv6only #ipv6
and twitter, ebay, and @BBCRD BBC but then I don't use Twitter any more.
Oh, and the Microsoft Teams seems to get stuck on 'Loading latest updates... in the meantime, you can still send and respond to messages'
Skype still needs IPv4, despite no longer being a peer-to-peer protocol. I don't use Skype regularly these days.
Aside from that, I can do my general day job without IPv4.
#IPv6 scores of big internet destinations (vaguely working day related)
Microsoft (inc GitHub,bing): 6/10
Google: 10/10
Twitter: 0/10
Mastodon: (depends on instance). 10/10
Amazon: 9/10
Cloudflare: 10/10
Reddit:0/10
Duckduckgo: 0/10
Apple: 10/10
Hetzner:10/10
Toggl: 0/10
eBay: 0/10
AliExpress:0/10
Scores based on regular user experience. It should all just work, the user shouldn't notice any lack of functionality with IPv4 disabled.
Or course, the systems I look after would score 10/10.
I find the score for Google is a bit too high considering the state of Google Compute Engine. Granted it has improved from non-existent a few years ago. But VMs still don't get enough IPv6 addresses to be useful in more interesting use cases. And during its years as an IPv4-only platform it caused services to go IPv4-only in order to host on GCE. Not all of those services have enabled IPv6 yet.
Cloudflare can provide dual-stack web service even if the backends are IPv4-only. But that is not enabled on all domains hosted on Cloudflare. For me that detail casts a little bit of doubt on the 10/10 score. But they can definitely score 9/10.
Reddit doesn't support IPv6 by default. But by simply adding an entry in the response policy zone on my DNS server I have been able to read Reddit using native IPv6. So I would have rated it 1/10.
