>I can think of some service provider network engineers that would gladly drop all of Argentina's IPv4 off the entire internet and "IPv6 prefix announcements welcome", if the business sides would let them do it.
replyYes, there's no shortage of employees that would vote to reduce their workload by removing their service offering, if you ask a physician here if the hospital should stop taking patients of X type, they'd be onboard, less work for them.
It's a dream though, try to make an AAAA request for any website, it's not there, even government websites.
>Something like this will probably start happening sooner than people think.
I'm even trying american companies, like citi.com, walmart.com, there's no AAAA records there.
>For as long as it makes organizational sense to continue using these devices, put them behind an OpenBSD box that performs NAT46 and DNS46, with IPv4 addresses statically mapped to IPv6 addresses, maybe ones that contain the MAC addresses of the devices.
This is an external facing service, so we don't control the devices or routes that patients and external physicians will be accessing the website.
>Tunneling
Yeah, I'm going to go this route, IPv4 tunnel, it's a horrible hack, but this is hacker news after all.
If the www. is prefixed or not, results for domains of Argentina differ. The results aren't almost-perfect like US, but IPv6 is apparently already somewhat prevalent in Argentina.
replyThe list from ChatGPT:
"This 2026 list ranks organizations by LinkedIn employee count, not revenue, and includes public bodies and universities as well as companies. I’ve kept the listed order; entries without a domain in the source are omitted."
