For me personally, IPv6 still feels like something that only exists in datacenters. I've had it for ages on my servers, but never in my life have I seen a home internet connection that supports it. I'm always surprised to see that I'm using IPv6 whenever I travel e.g. to Europe.

My experience is different: Comcast has been doling out IPv6 addresses for at least a decade, at least in San Francisco.
My T-Mobile phone gets IPv6 addresses.
My work and my swim club also have IPv6. It's pretty awesome.
It was "fun" discovering this the hard way a number of years ago when active US Android user count for a game we were supporting dropped 15% essentially overnight. The TCP stack in the client only did IPv4.
The challenge, ironically, was convincing management that adding IPv6 was the thing worth trying. After almost a week of getting nowhere (and almost 2 weeks of outage), I forced the issue by saying "Look, I'm doing this. I need one engineer for 2 days. If it doesn't work, then it doesn't work."
He got the change implemented in 2 hours. QA OKed it the next day. The topic never came up again.
AT&T also supports IPv6 although with comical prefix lengths. https://ssg.dev/ipv6-for-the-remotely-interested-af214dd06aa...
Huh? I have ATT fiber and have a /56.
Edit: n/m I guess I confused PD with having a larger subnet. :(
I have AT&T Fiber and it's been /64 since forever. I even called tech support who confirmed that they only provide /64 prefix length to home customers. How come did you manage to get a /56?
AT&T for years as well. Most of the lag is non-carrier businesses that don’t want to invest in profitless infrastructure changes.
Yeah, it’s weird. Even on brand new gigabit fiber connections in a tech city (Seattle). Quantum fiber doesn’t do native IPv6. WaveG / Astound allegedly supports it but the upstream connection from my LAN would not deal one out. Some packet sniffing seemed to indicate a weird bug.
Compounded by the fact that ISP customer support is worse than useless when it comes to any kind of networking knowledge.
Ultimately, this is the kind of standard that a federal regulation needs to enforce: when an ISP adds or updates a connection, it must support native IPv6. That would have solved this years ago.
My city (admittedly a lot smaller than Seattle) built a municipal fiber network. All new infrastructure. I was astounded to learn it was ipv4 only. And when I contacted support asking when IPv6 would be supported, they ghosted me.
I've had IPv6 with the last three ISPs I've had across California and Nevada. I can't honestly remember the last time I _didn't_ have IPv6.
I had it on my cable ISP, but we switched to fiber after it was put in earlier this year and no support there. Feels odd to step forward in one way and back in another.
Don't most of the mobile data networks use ipv6?
Mine definitely doesn't.
It is everywhere in Japan
Yeah, both my mobile and home internet are IPv6-native with IPv4 being provided through a tunnel (DNS64 for mobile, MAP-E for fibre)
woah this is my first time hearing about dns64, this seems really fascinating.
I might sound naive but why aren't we moving towards ipv6 if there is already a service which can make migrations easy I suppose for the end customer.
It seems that it is easy for a ipv6 client to connect to ipv4 lets say by using dns64 but it seems that the same isn't true for vice versa?
Now I am genuinely uncertain but Couldn't something like this be possible lets say by having both ipv4 and ipv6 running and the ipv4 could be through some tunneling software like serveo.net or the alikes and map-E seems to allow them to coexist too
I mean it seems that cloudflare warp can do this too if you want to connect to ipv6 and you have ipv4 but that adds a level of trust into cloudflare and etc. but still, do the benefits of ipv6 over ipv4 justify the migration of sorts or would these two things always coexist is a question/mystery
Like.. I searched the benefits and it seems that the truly great benefit is that everyone can get a ipv6 because of its higher size (basically limitless ipv6) as compared to ipv4 which are limited/exhausted right now.
IPSec seems to be another benefit which was optional and complex in ipv4 and its mandatory in ipv6 and it seems really nice to have encryption and so much more at a packet level.
What is the blocker? Like, as a server, do I really ever need a ipv4 if I have a ipv6 server, I think I might need it if I want everyone to view my website or etc. things on my server if their devices could be ipv4 and they can't access my ipv6 website I think but still aren't there any mitigations around it or sorts, I am kinda curious.
Big in Japan?
