A few months ago, one of the Linux distros I used released a kernel update with a bug that killed IPv4 connectivity. I tried to set up some kind of VPN to my basement server to work around that, but it didn't work. I even installed WireGuard, so I wasn't too far off. I gave up and decided to use the older not-buggy kernel.

I have created a DNS proxy for this problem, it will add the correct AAAA records on such domains.
Re: Using the Internet without IPv4 connectivity
#23ipv6 only machine still reaches ipv4 sites because dns64 upstream is just faking AAAA records ,makes it look like everything is native ipv6. this part of the trick is happening somewhere else which's not controllable. if dns64 breaks or stops doing the mapping properly then this might break
Re: Using the Internet without IPv4 connectivity
#24Slightly misleading title, this is more “getting to the IPv4 internet via an IPv6 tunnel through a VPS”. Also just called 4in6. Interesting nonetheless! We find at our ISP that if we break something with IPv4 we experience a very different type of support issue to if we break IPv6. Breaking v4 results in, broadly, a pretty hard “down” state. While folks are unhappy, it is at least simple. Breaking v6 results in weird…
There's certainly a long tail of IPv4, but the last time IPv4 broke at home, my wife didn't even notice since Google, Facebook, Apple/iCloud, and most CloudFlare-hosted properties all still worked over IPv6.

>spamhaus
Oh boy Spamhaus. I had to deal with them a few months back. For some reason, my VPS had ended up with its IPv6 addr. on the Spamhaus block list. I have no idea how it happened, the machine runs nothing with the capability to send email, and as far as I know, Digital Ocean even blocks SMTP, so it would be literally impossible for this machine to send any email. Spamhaus was not at all helpful in getting this resolved (and neither was DO for that matter).

#26Ha, I actually had to do this last year while setting up Arch Linux on my desktop.
I have to use this wifi dongle, but using IWD to connect somehow only gave me an ipv6 IP.
Most of the big sites worked, but trying to click links from a search engine was a 50/50 chance.
Thankfully, the Arch wiki was accessible, so I got it sorted out pretty quickly.

Spamhaus is a shaddy company from Switzerland and Andore, VERY SHADDY (I suspect blackmail).
digital ocean? I had to block all of digital ocean because scanners and script kiddies from there were zillions to scan/attacks my email server.

I can confirm that Steam requires IPv4. Also some games that require authentication to play do too.
I think microsoft(github.com)/steam are the main dominant corpos dragging the world backward, well from an IPv6 point of view. I though steam had now IPv6 addresses.
Don't forget IPv4 is favoring hardcore centralized online services.

#30If anyone wants to try / use IPv6, but their ISP does not provide it, Hurricane Electric (HE) has offered a tunnel service for many years now:
There are scrips available to bring up a tun device on your system (or router) and route traffic over it:
